Abstract
The polymerizations of hexadecene-1 were carried out at 40℃ in n-heptane by using the different catalysts (TiCl3·1/3AlCl3, MgCl2/TiCl4, Mg(OEt)2/DCE/DIBP/TiCl4) with various cocatalysts (diethyl aluminum chloride, triethyl aluminulm, triisobutyl aluminum, triisohexyl aluminum, tai-n-octyl aluminum). The activities of various catalyst systems for hexadecene-1 polymerization were reported. The poly(hexadecene-1) was fractionated with diethyl ether extraction and the soluble and insoluble parts have been characterized by the thermal analysis, intrinsic viscosity and molecular mass measurements, and 13C-nuclear magnetic resonance spectroscopy. From the analysis of polymer for various cocatalysts, it was found that the higher alkyl aluminum compound gave the higher stereoregularity and higher molecular mass.

여러가지 촉매(TiCl3·1/3AlCl3, MgCl2/TiCl4, Mg(OEt)2/DCE/DIBP/TiCl4)와 공촉매 (염화이에틸알루미늄, 삼에틸알루미늄, 삼이소부틸알루미늄, 삼이소헥실알루미늄, 삼노르말옥틸알루미늄)을 이용한 1-헥사데센의 중합을 40℃, n-헵탄중에서 행하였다. 여러 촉매계에 대한 촉매활성을 조사하였으며 폴리(1-헥사데센)을 디에틸에테르로 추출하여 불용성 및 용해성 부분으로 나눈 다음 열분석, 점도 및 분자량 측정, l3C-NMR등으로 분석하였다. 그 결과 유기알루미늄 화합물의 알킬기가 클수록 보다 높은 입체규칙성과 큰 분자량을 가진 중합체가 얻어진다는 것을 알았다.
