Abstract
The self-vulcanization, defined as a vulcanization which occurs without any curative, between ENR(epoxidized natural rubber) and CSM(chlorosulfonated polyethylene) was tested for a wide range of the blend(ENR/CSM) composition. Results from Rheometer(maximum torque, tan δ, and optimum cure time) showed that 70/30(ENR/CSM by weight) blend is subject to a most effective crosscure. Viscoelastic properties determined from a Rheovibron generally showed two glass transitions(Tg) for the blends, each indicating Tg of tole uncured(lower one) and cured rubber(higher one) In 70/30 blend, a single Tg corresponding to that of cured rubber was observed.

ENR(epoxidized natural rubber)과 CSM(chlorosulfonated polyethylene)의 자기 공가류를 검토하기 위하여 open roll에서 다양한 조성의 블렌드를 제조하였다. Rheometer측정(최고 torque, tan δ 및 최적 가류시간)결과 70/30(ENR/CSM) 중량조성에서 공가류가 가장 효과적으로 일어남을 확인할 수 있었다. 또한 가류물의 Rheovibron 측정I결과 블렌드는 -20℃ 및 40℃ 부근에서 두 개의 전이를 보였으며 이를 각각 비가류고무 및 가류고무의 Tg로 해석하였다. 또한 70/30 블렌드는 35℃ 부근에서 가류고무전이에 해당하는 단일 Tg를 보인다.
