Abstract
Ethylene-propylene copolymerizations with 3 types of Ziegler-Natta catalyst were carried out in a semibatch slurry reactor. The effects of monomer feed ratio on catalyst activity and copolymer composition were examined. From Fineman-Ross equation, monomer reactivity ratios were determined. Intrinsic viscosities and melting temperature of the copolymers were also measured.

3종의 Ziegler-Natta계 촉매를 사용하여 반회분형 slurry반응기에서 에틸렌-프로필렌 공중합을 행하였으며, 단위체 공급비에 따른 촉매활성의 변화와 생성공중합체의 조성의 변화를 검토하였다. 아울러 Fineman-Ross식으로부터 단량체 반응성비를 구하였으며, 생성공중합체의 고유점도 및 녹는점의 변화를 측정하였다.
