Abstract
The present disclosure relates to catalysts for making sulfur-containing polymeric materials. In particular, the disclosure provides catalysts, and the method of using the same, for making sulfur-containing polymeric materials through inverse vulcanization at a temperature that is lower than 150° C.
Claims13
A catalyst for an inverse vulcanization is a compound selected from a group consisting of tetramine, thiazole, thiophosphate, guanidine, mercaptobenzothiazole, thiourea, xanthate, and sulfenamide, or a sodium, potassium, or zinc salt thereof, wherein the inverse vulcanization is polymerized at a temperature of 100° C. to 150° C.
