Abstract
The copolymerization of propylene and 1-hexene with MgCl2/EHA/TiCl4-TEA system has been studied in which MgCl2 was dissolved in 2-ethyl-1-hexanol(EHA). The effects of catalyst preparation conditions and polymerization conditions on the activity and composition of copolymers have been investigated. The maximum activity was obtained at [TEA]/[Ti]=60 and the content of 1-hexene was constant irrespective to [TEA]/[Ti]. The monomer reactivity ratio was dependent on the catalyst preparation conditions and the presence of Lewis bases. With addition of Lewis bases, the activity and 1-hexene contents in copolymer decreased. Thermal properties and mechanical properties of copolymer were also investigated.

염화마그네슘을 2-ethyl-1-hexanol(EHA)에 녹인 용액으로부터 제조한 사염화티탄 담지촉매로 프로필렌과 1-헥센의 공중합을 행하였다. 이때 촉매의 제조 조건 및 중합 조건 등에 따른 촉매의 활성과 공중합체의 조성을 조사하였으며, 아울러 첨가제인 Lewis염기의 영향도 조사하였다. 프로필렌/1-헥센 공중합에서 [TEA]/[Ti]의 농도비가 60일 경우에 최대의 활성을 나타내었으며, 공중합체의 1-헥센 함량은 [TEA]/[Ti]의 농도비에 관계없이 일정하였다. Kelen-Tudos 방법으로 구한 단량체의 반응성비는 촉매의 제조조건 및 Lewis염기의 유무에 따라 변하였다. Lewis염기를 첨가함에 따라 촉매의 활성과 1-헥센의 함량은 감소하였다. 또한 공중합체의 열적 성질과 기계적 성질도 조사하였다.
