联邦德国汉堡大学应用化学系的瓦尔特·卡明斯基(Walter Kaminsky)先生研制成功一种新型高效催化剂。该催化剂的基本组份是混有氧丙环铝(aluminoxane)的锆化物。氧丙环铝是由5～20个交替连接在一起的铝原子和氧原子构成,其中60%具有环状结构,40%以链状结构存在。这种催化剂具有如下主要特点: (1)具有极高的反应活性; Walter Kaminsky, Department of Applied Chemistry, University of Hamburg, Federal-Mogul, Germany, successfully developed a new and highly efficient catalyst. The basic component of this catalyst is a zirconium compound mixed with aluminoxane. Oxypropyl aluminum is composed of 5-20 aluminum atoms and oxygen atoms alternately connected, of which 60% has a cyclic structure and 40% exists in a chain structure. This catalyst has the following main features: (1) has a very high reactivity;
