摘要

Metallcoene觸媒為近年來發展之高效率觸媒。此類觸媒具有高聚合活性及單一均勻的活性部位，可廣泛的應用在各類烯烴單體之單質聚合及共聚合反應。此外若選擇適當之Metallcoene觸媒，可製得具有立體規則性及分子量雙峰之特殊聚烯烴高分子。本文探討以商業化（Cp2Zrcl2）及工研院化工所新發展的（CpTpZrcl2）觸媒來聚合聚乙烯高分子，並研究此類合反應在不同反應條件下之動力學，由此動力學數據進而掌握最適當之反應條件以供日後製程放大之用。

Metallocene catalysts are high efficient catalysts developed in the recent years. These catalysts have the following unique properties: (1) Higg activity for polymerization. (2) A single and homogeneous catalyst system. (3) Applicable to a wide variety of monomers comonomers polymerization. Otherwise, we can produce stereoregular and bimodel polyolefins through a proper selection of catalyst system. This paper will investigate the kinetic behavior of the ethylene polymerization by CpZrCl2/MAO and CpTpZrCl1/MAO metallocene catalysts.
These catalyst were obtain from eommercial and from Union Chemical Laboratories, Industrial Technology Research Institute respectively. The kinetics in different conditions are studied. From the catalytic polymerization kinetic data, hopely we can obtain the optimal condition for scale-up process.
