Abstract
Hygrothermally decomposed polyester-urethane (HD PUR) was mixed at concentr ations up to 20 pphr with a styrene/butadiene rubber (SBR), using an effici ent vulcanisation system. Changes in the cure behaviour were followed by vu lcametry, plate-plate rheometry, and differential scanning calorimetry. It was found that the degree of crosslinking was increased by the incorporatio n of HD PUR, which acts as an accelerator in SBR stocks. Increasing crossli nking resulted in higher stiffness and strength and was accompanied by a re duction in elongation at break and swelling index. (C) 2001 IoM Communicati ons Ltd.
