The invention relates to high-activity catalysts for olefin polymerization, to efficient methods for producing them, and to efficient methods of using the catalysts for producing high-quality polyolefins. The olefin polymerization with the catalysts does not require a large amount of an organic aluminium compound, and the residual metal in the polyolefins produced is much reduced. The catalysts are characterized by containing a product as prepared by contacting any of clay, a clay mineral and an ion-exchanging layered compound, an organic silane compound, and water with each other, or by containing a silane compound-processed clay.
本发明涉及用于烯烃聚合的高活性催化剂、生产催化剂的有效方法以及使用催化剂生产高质量聚烯烃的有效方法。使用这种催化剂进行烯烃聚合不需要大量的有机铝化合物,生产的聚烯烃中的残余金属也大大减少。这些催化剂的特点是含有通过将粘土、粘土矿物和离子交换层状化合物、有机硅烷化合物和水中的任何一种相互接触而制备的产品,或含有硅烷化合物处理过的粘土。
