FIELD: polymers. ^ SUBSTANCE: stabilizing agent composition for foaming plastics of halogen-containing polymers contains at least one halogen-containing hydroxyacid salt, for instance sodium or ammonium perchlorate and at least one pore forming agent, wherein content of two components is 0.1 mass % based on total composition mass, wherein composition contains at least one halogen-containing hydroxyacid salt in amount of 0.01-50 mass % and at least one pore forming agent in amount of 0.5-50 mass % as calculated to total composition mass. Moreover composition contains less than 10 % salt crystallites having size more than 3 mum as calculated to total content of halogen-containing hydroxyacid salt. Stabilizing agent composition is useful in polymer composition for foaming plastics such as foamed mould articles, containing at least halogen-containing polymer. ^ EFFECT: foaming plastics with improved original color. ^ 18 cl, 4 ex, 4 tbl |
