FOAMABLE POLYOLEFINIC COMPOSITION (VARIANTS), COMPOSITION OF STABILIZING REAGENT FOR POLYOLEFIN FOAMS, PRODUCT FROM FOAMID POLYOLEFIN AND METHOD OF PREPARING POLYOLEFIN FOAM Russian patent published in 2001 - IPC

FIELD: manufacture of various types of size increasing products. SUBSTANCE: compositions comprise combined stabilizing reagent intended for preventing shrinkage and expansion after cooling. Composition of stabilizing reagent comprises at least one compound which is essentially ester acid and at least one compound selected from group consisting of higher alkyl amines, fatty acid amides and/or fatty acid esters. Addition of at least two compounds to polyolefinic composition as stabilizing reagent in amount from 0.1 to 15% with respect to weight of polymeric resin minimizes shrinkage and expansion in foamed material after cooling. EFFECT: improved properties of the polyolefinic composition. 30 cl, 10 ex, 1 tbl
