Abstract
Sulfur vulcanizable acrylic elastomers were prepared by the copolymerization of ethylacrylate and ethylidenenorbornene with suspension polymerization system.Redox system was used as radical polymerization initiator. Minimum value was observed at around 6°C in tensile strength and elongation of the vulcanizates when the reaction temperatures were varied from2 to 21°C. The polymer prepared at 2°C gave the best result in physical properties of the vulcanizate.When vulcanized with polysulfide cure system they showed better heat resistance than those of monosulfide cure system even after14days of heat aging at150°C.
