METHOD FOR OBTAINING PLASTICISER FOR POLYVINYL CHLORIDE COMPOSITION Russian patent published in 2018 - IPC C08L27/06 C08K5/101 C08K13/02

Abstract RU 2643996 C1

FIELD: chemistry.

SUBSTANCE: method consists in preparing ester of glycerol and monobasic carboxylic acid in the presence of a catalyst using the azeotropic distillation of water. Herewith calcium hydroxide is used as a catalyst, and oleic or stearic acid is used as monobasic carboxylic acid. The plasticiser is produced at a molar ratio of glycerol, acid, and calcium hydroxide of 1:1.12:0.06.

EFFECT: simplification of the method for obtaining a plasticiser and increasing its plasticising properties.
