SULFOXIDES OR SULFONES, GRAFTED POLYMERS (VARIANTS), POLYMERIC COMPOSITION, METHOD FOR GRAFTING AND METHOD FOR STABILIZING POLYMERS

摘要

FIELD: chemistry of polymers, chemical technology. ^ SUBSTANCE: invention relates to sulfoxides or sulfones grafted on polymers, polymeric compositions, a method for grafting and method for stabilization of polymers. Invention describes polymers comprising a grafted compound of the formula (I): [R1-SOm]n-R-SOp-R2 (I) wherein total symbols have values given in cl. 1 of the invention claim and represents a composition comprising thereof, a method for grafting compound of the formula (I) on polymers and a method for stabilization of polymers. Polymers comprising grafted sulfoxides or sulfones possess high stability against oxidative, thermal, dynamic destruction caused by the light effect and/or destruction caused by ozone effect. ^ EFFECT: improved preparing method, improved and valuable properties of polymers. ^ 14 cl, 14 tbl, 24 ex
