Abstract

Abstract Cycloalkylthioamines per se are moderately active accelerators. When used in conjunction with the benzothiazole accelerators, these thioamines act as prevulcanization inhibitors with cure activating properties, and generally, increase the crosslink density of the vulcanizates. The inhibition action of the cycloalkylthioamine may be due to its activity as a BtSH scavenger and also to its ability to reduce the number of the labile sulfur atoms, thereby the reactivity, of the more active polythiobenzothiazole intermediates. In addition to these capabilities the inhibition action of PVI in a benzothiazole sulfenamide-accelerated stock may be due to its ability to react with the free amine liberated during vulcanization. The relation of the curing properties of the cyclohexylthioamines to the structure of the amine moiety is analogous to the cases of dithiodiamines and 2-(imino)dithiobenzothiazoles as vulcanizing agents, or N-substituted-2-benzothiazole sulfenamides as accelerators. The relative curin...
