The scope of this paper is to review peroxide curing of diene elastomers. At high dicumyl peroxide loading and high curing temperature, changes in the crosslinking mechanisms were observed. Both Abstraction of allylic hydrogen and addition to the double bond can act as mechanisms of crosslinking. IR spectroscopy reveals a significant decrease in double bonds, and a new relaxation at temperatures above the Tg of the elastomers is present.
