摘要

自從利用有機茂金屬觸媒系統進行聚合反應以來，非極性之烯烴單體與極性單體藉由過渡金屬錯合物進行直接共聚合反應一直是大家努力的方向，本研究利用以架橋的有機茂金屬Et(Ind)2ZrCl2/MAO觸媒系統作為催化劑，進行乙烯與極性單體氯基十一烯之直接共聚合反應，並控制其反應變因進行研究。發現以[Al]/[Zr]=5000，60℃極性單體濃度為25mmole條件下反應時-Cl在共聚物中之官能基含量可達3.71mole%，在本研究中並不需使用任何之保護基或預錯合的方式，直接共聚合的方法即可成功的合成出乙烯與11－氯基－十一烯共聚物，且此共聚物之鹵素官能基可任意的藉由化學反應改變成多種官能基，以利各種用途之需。

By using the metallocene catalyst system, people devote themselves to proceed copolymerization of olefin monomer and polar monomer in recent year. This paper presents the direct copolymerization of ethylene and 11-chloro-undecene via the bridge Et(Ind)2ZrCl2/MAO catalyst system. And the results of the various reaction factors are reported. We found when the ratio of [Al]/[Zr] was 5000 and the concentration of 11-chloro-undencene was 25 mmole at reaction temperature 60℃, the functional group contents of ploy(ethylene-co-11-chloro-undecene) could reach 3.71mole%. In this paper, we could directly synthesis ethylene and 11-chloro-undecene copolymer without using any protecting group or pre-complex method. The halide group in this copolymer could easily change to many kinds of functional group by using organic chemical reaction for many applications.
