ABSTRACT:
Polymeric thiosynergists, such as poly[2-(alkylthio)ethyl methacrylate], are stabilizers for organic materials subject to oxidative, thermal and/or light induced deterioration. These polymeric synergists are made by normal free radical polymerization of the corresponding (alkylthio)alkyl polymerizable esters. The esters are prepared by conventional esterification procedures. These compounds are used in conjunction with phenolic antioxidants to stabilize organic materials, particularly polyolefins and hydrocarbon compositions, against the deleterious effects of heat and oxygen.
