In one variant of the implementation of the molar ratio between aluminum and total external electron donor is 3:1.

As to my surprise suddenly discovered applicants neimagazine system catalysts with bidentate internal electron donor, such as simple fluids, succinate, alkoxybenzyl and/or ester diol can be converted into a self-extinguishing compositions of the catalysts resulting from the use of any of the above-mentioned external electron donor. In addition, as to his astonishment applicants, controlled by keeping the total molar ratio between aluminium and the external electron donor in the range from 0.5:1 to 4:1 best way yields a system of catalyst, which is characterized by high productivity with excellent ease of use and is self-extinguishing. In accordance with the use herein of "self-extinguishing" a catalyst is a catalyst which shows reduced activity: (1) at a temperature greater than approximately 100°C, in comparison to the activity observed under normal conditions of polymerization, or (2) at a temperature greater than 85°C, in comparison to the activity observed in the case of replacement of an agent that limits activity (AAO) with the same molar amount of an agent that determines the selectivity, (AOC). In addition, in order practical standard m who should say what what if the polymerization process, in particular gas-phase polymerization in the fluidized bed, implemented under normal conditions of processing, can be interrupted with the resulting collapse of the layer without the occurrence of adverse effects in respect of agglomerating the polymer particles, the composition of the catalyst is considered to be "self-extinguishing".

In order standardized measures polymerization activity at elevated temperatures used in this document, the catalyst activity regulate to compensate for differences in the concentrations of monomer due to temperature. For example, in the case of conditions of the liquid phase (suspension or solution) polymerization will include a correction factor to account for the reduced solubility of propylene in the reaction mixture at elevated temperatures. That is, the catalyst activity "normalize" to compensate for the reduced solubility in comparison with what takes place at low temperature, especially when the standard is 67°C. the "Normalized" activity at the temperature T or a_Tdefined as the measured activity or the amount (mass of polymer/weight of catalyst/hour) at a temperature T activity (T) multiplied by a correction factor for the concentration of [P(67)]/[P(T)], where [P 67] represents the concentration of propylene at 67°C, and [P(T)] represents the concentration of propylene at a temperature T. the Equation for the normalized activity is presented below:

$$N\mathrm{about}pm\mathrm{and}l\mathrm{and}C\mathrm{about}\mathrm{in}\mathrm{and}nn\mathrm{and}I\mathrm{and}Kt\mathrm{and}\mathrm{in}n\mathrm{about}\mathrm{with\; a}tb({\mathrm{And}}_T)=\frac{\left[P(67)\right]}{\left[P(T)\right]}\times \mathrm{and}Kt\mathrm{and}\mathrm{in}n\mathrm{about}\mathrm{with\; a}tb(T)$$

In equation activity when the temperature T is multiplied by the ratio between the concentration of propylene at 67°C and the concentration popeline at temperature T. the Resulting normalized activity (A), adjusted to account for the reduction in the concentration of propylene with increasing temperature, can be used to map the activity of the catalyst under varying temperature conditions. Correction factors for terms used in liquid-phase polymerization, measured and brought forth.

As suggested correction factor activity during polymerization increases linearly with increasing concentration of propylene in the used conditions. The correction factor depends on the used solvent or diluent. For example, the correction factors listed previously, are common With_6-10aliphatic hydrocarbon mixture (Isopar™E, available at Exxon Chemical Company). In terms of conducting the gas-phase polymerization, the solubility of the monomer is usually not important, and in General to account for temperature differences activity is not correct. That is, the activity and the normalized activity will constitute one and the same.

"The ratio of normalized activities" is defined as A_T/A₆₇where a_Trepresents the activity at the temperature T, and A₆₇represents activity at 67°C. This value can be used as an indicator and the changes of activity depending on the temperature. For example, as demonstrated by the magnitude And₁₀₀/A₆₇0.30 , the activity of the catalyst at 100°C is only 30 percent of the catalyst activity at 67°C. As determined at 100°C the ratio a/a₆₇equal to 35% or less, and usually provides the receiving system of the catalyst, which is self-extinguishing system.

In any of the above variants of realization of the external electron donor may include from about 50 mole percent to about 99 mol% (or any value or subrange between data values) of the AOA and from about 1 molar percent to about 50 mol% (or any value or subrange between these values) AOC. In the case of polymeric or oligomeric agent, limiting activity, (such as poly(allenglish) and/or an ester of poly(alkalophiles)) the external electron donor may include from about 5 mole percent to about 90 mole percent (or any value or subrange between data values) of the AOA and from about 10 mole percent to about 95 mole percent (or any value or subrange between these values) AOC.

The molar ratio between aluminium and the AOC may, at ditsa in the range from 750:1 to 1.25:1 (or to make any value in between these values) or from 150:1 to 1.25:1 or 80:1 to 1.5:1 or 40:1 to 1.67:1, or from 20:1 to 2.5:1 or 13:1 to 5:1.

The molar ratio between aluminium and the AOA can be in the range from 20:1 to 0.5:1 (or to make any value in between these values) or 6.7:1 to 0.5:1, or from 5.7:1 to 0.52:1 or from 5:1 to 0.62:1, or from 4.4:1 to 0,71:1 or from 5.3:1 to 0.5:1. The molar ratio between the external electron donor and the titanium can be in the range from about 5:1 to about 100:1. In one embodiment, the implementation of the molar ratio between the total external electron donor and the titanium is 30:1. If the content of the polymeric or oligomeric agents, limiting activity, (such as poly(allenglish) and/or an ester of poly(alkalophiles)) the molar ratio between aluminium and the AOA can be in the range from 200:1 to 1:1 (or to make any value in between these values) or from 70:1 to 1:1 or 50:1 to 1.5:1 or 30:1 to 2:1 or 20:1 to 2.5:1 or 17:1 to 3:1. The molar ratio between the total external electron donor and the titanium can be in the range from about 2:1 to about 100:1.

The present composition of the catalysts produce polypropylene composition, which is characterized by high rigidity and high isotacticity (i.e., low content of fraction soluble in xylene). As you can imagine without the desire to link sabakami any particular theory, the molar ratio between aluminium and the external electron donor in the results of the composition of the catalyst, which reproduces the property of fire extinguishing catalysts of the third generation, which as electron donor used esters of benzoic acid, without giving the resulting polymer a strong smell of benzoates. In addition, the activity of the present compositions of the catalysts with the activity of conventional catalysts fourth generation or exceed her without the use of internal electron donor on phthalates basis. Thus, the present compositions of the catalysts are showing signs of fire extinguishing catalysts third generation while meeting or exceeding the activity of the catalysts of the fourth generation.

(3) measurement of the value XS

The percent soluble in xylene fraction (% XS) in polypropylene (PP) is a property of the material listed in multiple tables with the specifications of the products and methods of measurement set out in document ASTM method D 5492-98. In the method determine the fraction of PP sample, which is soluble in o-xylene at 25°C. the Soluble fraction shows good correlation with the percentage of amorphous fractions in PP. The content of the amorphous fraction is closely related to the operational characteristics of the final product, and is a critical factor for process control. To measure the % fraction of polypropylene (PP), soluble in trichlorobenzene, (% TCB) and establish a correlation between this value and % fraction soluble in xylene, standards-based PP use the tool fixture.
