Abstract
The ENR(epoxidized natural rubber) blends with CR(chloroprene rubber) were prepared by master batch process. Viscosity, core characteristics, resilience, flex and ozone crack resistance were subsquently determined. Dynamic measurement(rheovibron) showed a single tan δ peak for the blend, and the peak monotonically moved toward the lower temperature with the increasing content of CR. It was also found that the ozone crack resistance was significantly improved upon blending a small amount(10%) of CR.

Master batch법으로 ENR(epoxidized natural rubber)/CR(chloroprene rubber) 블렌드를 제조, 이들의 점성 및 가류특성, resilience, 굴곡저항 및 내오존 특성들을 검토하였다. 동적특성 측정(rheovibron)으로부터 ENR/CR 블렌드는 단일 tan δ peak를 나타냄을 확인하였고, peak의 위치는 CR의 함량증가와 더불어 저온쪽으로 이동함을 볼 수 있었다. 아울러 ENR의 내오존성은 소량의 CR (10%) 첨가로 크게 개선되었다.
