FIELD: chemistry.
SUBSTANCE: invention relates to a heavy metal-free stabiliser for halogen-containing polymers and can be used to stabilise halogen-containing polymers, particularly for preventing undesirable pink colouration, and moulded articles containing said stabiliser composition. The stabiliser composition for halogen-containing polymers based on isocyanurate, which does not contain heavy metals, includes as basic components at least one isocyanurate, at least one dihydropyridine and at least one perchlorate salt. The moulded article made from the halogen-containing polymer contains the stabiliser composition.
EFFECT: invention enables to stabiliser halogen-containing polymers without using heavy metals and increases stability thereof against sunlight and artificial light.
