Abstract

The influence of hygrothermally-degraded polyester urethane (HD-PUR) waste on chloroprene rubber (CR) has been studied giving special attention to curing behaviour, mechanical properties and dynamic mechanical behaviour. The presence of primary and secondary amines in HD-PUR, did not increase the cure rate of CR. The mechanical properties of chloroprene vulcanizates were improved upon HD-PUR addition. The strain-induced crystallisation of CR did not show any deviation upon the addition of HD-PUR. Crosslink densities calculated from swelling studies, stress-strain behaviour, and modulus measurements are found to increase upon HD-PUR addition and showed similar trend. The glass transition temperature (Tg) did not show any significant change, with the addition of HD-PUR. Scanning electron microscopic studies have been done in order to have an insight into fracture behaviour of the samples and to analyse the microstructure of the blends.
