Abstract
Terpolymerizations of propylene/1-hexene/1-hexadecene had been carried out with high-isospecific and nonisospecific catalysts. For high-isospecific Solvay TiCl3-Cp2TiMe2 catalyst system, polymerization rate accelerated and incorporation of 1-hexone and 1-hexadecene in terpolymer increased when feed ratio of 1-hexone and/or1-hexadecene increased. In contrast, catalyst activity and comonomers content decreased with addition of comonomers for nonisospecific MgC12/TiCl3-TEA catalyst system. These phenomena might be explained with the concept of monomer diffusion limitation.

고입체규칙성 촉매와 비입체규칙성 촉매를 이용하여 프로필렌/1-헥센/1-헥사데센 삼원공중합을 행하였다. 고입체규칙성인 Solvay TiC13-Cp2TiMe2를 사용한 삼원공중합에서 1-헥센과 1-헥사데센의 단량체 공급비가 증가할 때 중합속도가 가속화되고 삼원공중합체 내의 1-헥~센 및 1-헥사데센의 함량이 증가하였다. 반면에 비입체규칙성 MgCl2/TiCl3-TEA 촉매계를 사용한 경우에는 공단량체가 첨가됨에 따라 촉매활성과 공~단량체의 함량이 감소하였다. 이러한 결과를 단량체 확산의 개념으로 설명하였다.
