Abstract : The stress relaxation properties of poly(ethyl acrylate) and poly (dimethyl siloxane) were investigated under conditions where oxidative degradation was minimized. The relaxation observed is thought to result from the continued approach to equilibrium of the network chains with cooperative thermal motion. These elastomers, representing two new classes of polymer, and two new types of crosslinking, were found to behave surprisingly like natural rubber and butadiene-styrene copolymer. (Author)
