изобретение относитс  li стабилизироваМным композици м на основе полистиролов, в частности ударопрочных полистиролов (сополимеры стирола с каучуком), и может найти применение дл  получени  изделий с повышенной стойкостью к действию тепла и света.The invention relates to the stabilization of polystyrene-based compositions, in particular impact polystyrenes (copolymers of styrene with rubber), and can be used to produce products with enhanced resistance to heat and light.

Известно, что дл  термостабилизации стирольных полимеров примен ют различные органЯчебкие соединени  типа алкилфенолйй, фосфитов, в качестве эффективных светостабилизаторов используют производные бепзтриазола .It is known that various organoleptic compounds such as alkylphenol and phosphites are used for thermal stabilization of styrene polymers, and they are used as effective light stabilizers.

Предложено в качестве стабилизирующей добавки к ударопрочному полистиролу примен ть ди-(4-фениламинофенпл)-карбонат, условно названный С-7.It has been proposed to use di- (4-phenylaminophenpl) -carbonate, conventionally called C-7, as a stabilizing additive to impact-resistant polystyrene.

золе. Из полученного раствора отливают тонкие пленки, которые прогревают нри 180 и 225°С. Определ ют врем  в минутах до по влени  кислородсодержащих групп, фиксируемое как период индукции. Результаты приведены в табл. 2.ash. From the resulting solution, thin films are cast, which are heated at 180 and 225 ° C. The time in minutes before the occurrence of oxygen-containing groups, recorded as the induction period, is determined. The results are shown in Table. 2
