where the group RIIIidentical or different, represent hydrogen or C1-C18hydrocarbon group; groups of RIVidentical or different, have the same meaning as RIIIexcept that they cannot be hydrogen; each of the groups RIII- RIVmay contain heteroatoms selected from Halogens, N, O, S and Si, and the radicals RVidentical or different, are selected from the group consisting of hydrogen; Halogens, preferably C1 or F; C1-C20alkyl radicals with a straight or branched chain; C3-C20cycloalkyl,6-C20and Rvcan be connected to each other to form a condensed cyclic structures, saturated or unsaturated, optionally substituted, RVIradicals selected from the group consisting of halogen, preferably C1 or F; C1-C20alkyl radicals, linear or branched; C3-C20cycloalkyl, C6-C20aryl, C7-C20alkalinic and C7-C20Uralkalij radicals; the radicals RVand RVIoptionally contain one or more heteroatoms as substitutes for carbon or hydrogen atoms, or both. Also the claimed catalyst and method for (co)polymerization. These components of the catalyst is able to provide propylene polymers, which due to the high values of resistance to dissolution in xylene exhibit a wide range of stereoregularity. 3 C. and 20 C.p. f-crystals, 4 PL.
