SULFOXIDES OR SULFONES, GRAFTED POLYMERS (VARIANTS), POLYMERIC COMPOSITION, METHOD FOR GRAFTING AND METHOD FOR STABILIZING POLYMERS Russian patent published in 2007 - IPC C08C19/20 C08F8/34 C07C317/06 C07C321/16 C07D303/26 C07D303/16 C07D249/18 C07D233/42 C07D405/12 C07F7/18 C08L51/04 C08L101/00 C09K15/04

Abstract RU 2291874 C2

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-SO_m]_n-R-SO_p-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.
