Known technical solution SU 963886, 1983, in which the multilayer fire-resistant material comprises a textile substrate and a double-layer coating deposited on this basis. Two-layer coating is made on the basis of plasticized polyvinyl chloride containing a mixture of antimony trioxide and halogen-containing flame retardant. The outer layer of this coating contains 9-29 parts by weight of antimony trioxide and 1-10 parts by weight of a halogenated flame retardant. The inner coating layer contains 100 parts by weight of polyvinyl chloride 1-20 parts by weight of antimony trioxide and 19-80 parts by weight of a halogenated flame retardant. The disadvantage of this technical solution is the migration of the flame retardant on the surface of the polymer material, which reduces the fire resistance of the material. In addition, this material is characterized by low resistance.

Lubricant is obtained by interaction of alpha-branched saturated monocarboxylic C10-C28-acids with polyhydric alcohol at 180-220°C in molar ratio of 1:(1-2) in presence of bivalent metal oxides: CaO, PbO, ZnO, MgO, BaO or two-component mixture thereof in ratio of 0.25-1:0.5-1, in amount of 0.5-2.0 mass % calculated as total reaction mass. As polyhydric alcohol ethylene glycol, glycerol, polyglycerol, which represents slop from glycerol distillation, are used.

EFFECT: articles with increased extension strength, elongation, heat resistance, improved appearance, decreased brittle point; resin composition assortment expansion.

FIELD: organic chemistry, in particular polymers.

SUBSTANCE: invention relates to plasticized composition based on emulsion polyvinylchloride, i.e. plastisols useful in production of polymeric articles. Plastisol contains emulsion polyvinylchloride, ester plasticizer such as dioctylphtalate, chalk, titanium dioxide, epoxy resin, barium stearate, and additionally contains metal-containing lubricant with acidic number at most 3 mg KOH/g. Lubricant is obtained by interaction of alpha-branched saturated monocarboxylic C10-C28-acids with polyhydric alcohol at 180-220°C in molar ratio of 1:(1-2) in presence of bivalent metal oxides: CaO, PbO, ZnO, MgO or two-component mixture thereof in ratio of 0.25-1:0.5-1, in amount of 0.5-2.0 mass % calculated as total reaction mass. As polyhydric alcohol ethylene glycol, glycerol, polyglycerol, which represents slop from glycerol distillation, are used. Composition of present invention is useful in production of thin-layer polymeric articles.

EFFECT: decreased viscosity rising during storage; drier surface of finished articles; resin composition assortment expansion.

FIELD: agriculture; development and production of multilayer films materials for packing of solid rennet cheeses.

SUBSTANCE: the invention is dealt with development of the multilayer film materials intended for packing of solid rennet cheeses and serve as a selective barrier to the gases formed inside a packing at a cheese maturing and stayed in the environment. The film consists at least of three layers: a barrier layer based on PVDC and limiting accessO2 into the packing; a contact layer out of chemically inert polymer contacting the cheese; an adhesion later located between them. The film changes its structure and properties in the process of maturation of the cheese packed into it: lactic acid bacteria annihilate corpuscles of the filler (carbohydrates, starch and-or sodium alginate) in the contact layer of the film of a film, which turns into a porous structure, that speeds up migration of CO2 from the packing into the adhesion layer, where it is partially absorbed by chitin; in the opposite direction migration of biocides becomes possible (an ascorbic acid, nisin, lysozyme) preventing a microbial spoilage of a cheese, this takes place at a final stage of a maturation, when the vital functions of the lactic acid bacteria is decreasing and biocides influence them insignificantly. The film acts as an active packing material, which structure and properties are regulated by the running of microbiological processes of the cheese maturation.

EFFECT: the invention ensures action of the film as an active packing material, the structure and properties of which are regulated by the running of microbiological processes of the cheese maturation.
