Abstract
The scope of this paper is to review peroxide curing of diene elastome rs. At high dicumyl peroxide loading and high curing temperature, chan ges 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 do uble bonds, and a new relaxation at temperatures above the T-g of the elastomers is present.
