Abstract

The freezing point depression of DCP-cured SBR with varying styrene content swollen in benzene was measured. The Kuhn parameter, aH, decreased with increasing styrene content at the same swelling equilibrium concentration of polymer in swollen rubber vulcanizates, Ce. The dependence of aH on styrene content and Ce could be explained qualitatively on the basis of the recent theory of semi-dilute polymer solutions. It was found from the difference in values of aH that the three-dimensional structure of a degraded network at the initial stages of degradation may be different from that at the latter stages.
