RESIN COMPOSITION Russian patent published in 2005 - IPC

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.
