摘要

全球塑膠製品將近有40%為聚烯烴材料所製，產品廣泛應用在民生消費、醫療衛生、工具零件以及各類運輸交通裝置等等，著實影響科技與社會的發展。在聚烯烴產品的開發中，聚合單體與共單體、觸媒組合、聚合與加工製程這三個關鍵因子使得聚烯烴材料具有不同的結構與物性，而材料的多樣性變化，造就了不同的應用情境與實用性。本文介紹聚烯烴觸媒的種類與發展概況，以及透過載體製備、反應壓力、反應溫度與氫氣量等實驗參數，來了解聚烯烴合成時關鍵因子對產物的影響。

Nearly 40% of the global plastic products are made of polyolefin materials. They are widely used in packing consumption, medical care and various mechanical parts in industry and transportation, which strongly affects the social and economic development as well as technological advancement. In the development of new type of polyolefins, monomer/comonomer, catalyst, and polymerization process are the three key factors governing different composition, structures and physical properties of polyolefin materials. The preparation of polyolefin materials with diverse physical and mechanical properties are widely used in various development of products. This article aims to introduce three types of polyolefin catalysts, co-catalyst, and carrier and discuss the polymerization experiments, including carrier preparation, reaction pressure and temperature as well as hydrogen dosage, to understand the influence of those parameters during polyolefin polymerization.
