FIELD: chemistry.
SUBSTANCE: stabilising composition for resistant to atmospheric impacts halogen-containing thermoplastic resins, and polymer composition based on halogen-containing thermoplastic resins, containing said stabilising composition, which includes stabilising calcium compound representing calcium hydroxide and/or calcium oxide, whose surface can probably be modified, or calcium salt of organic carboxylic acid, or mixture of two or more such compounds at least one dye or pigment or their mixture, dye or pigment giving halogen-containing thermoplastic resin colour parameters L≤95, a=0 ± >1 or b=0 ± >1, or a=0 ± >1 and b=0 ± >1, and at least one isocyanurate, which has hydroxyl groups, content of β-diketone, or β-diketone salts, or their mixtures in stabilising composition constituting less than 0.1 wt % of all stabilising composition. Polymer compositions are obtained by mixing said ingredients and are used for manufacturing formed products.
EFFECT: obtaining coloured polymer compositions resistant to atmospheric impacts.
