Abstract

The difference in the crosslinking reactivity between epichlorohydrin rubber (CHR) and its copolymer (CHC) with2anilino-4, 6-dithiol-s-triazine (AF) has been explained from the oxyethylene group which is in CHC structure.The oxyethylene group tends to increase the reactivity of thiol group of AF and to increase the compatibility of AF to CHC.Then, oxyethylene-containing compounds such as polyethylene glycol and its monolauryl ether have been selected as an excellent accelerator for the CHR-crosslinking with AF.Polyethylene glycol monolauryl ether has been found also to accelerate the crosslinking reaction with AF in chlorinecontaining polymers such as acryl rubber, butyl rubber, chlorinated polyethylene, and poly (vinyl chloride).
