Abstract RU 2365601 C2

FIELD: chemistry.

SUBSTANCE: foamable composition for obtaining foamed products contains polyvinylchloride, primary plasticiser, if necessary, other additives and as alkyl ester of benzoic acid, isononyl ester of benzoic acid in amount from 5 to 95 wt %, counting per weight of all available plasticiser, which constitutes 10 to 400 wt.p. per 100 wt.p. of polyvinylchloride. Method of product obtaining, which contains at least one foamed layer of polyvinylchloride consists in application of foamed composition on carrier, before and after application it is foamed and in conclusion it is thermally processed. Product represents covering for floors, artificial leather and wallpapers.

EFFECT: reduction of composition viscosity, temperature of its gelatinisation, which results in simple and quicker composition processing.
