乙烯的聚合通常耍在1000大氣壓以上,溫度200°下進行,最近德國Ziegler和其同工作者發表一系列研究結果,他們找到有機鋁化合物可以使乙烯類化合物特别是乙烯在很低的壓力或常壓下進行聚合,因而製造聚乙烯的方法大為簡化,所用催化劑为三乙鋁,其反應如下:

Polymerization of ethylene is usually performed above 1000 atmospheres and at a temperature of 200 ° C. Recently, Ziegler and colleagues in Germany published a series of research findings that found that organoaluminum compounds can make vinyl compounds, especially ethylene, at very low pressure or often The polymerization was carried out under pressure so that the method of producing polyethylene was greatly simplified. The catalyst used was triethylaluminum and the reaction was as follows:
