【Abstract】 This paper summarized the recent years’ progress on R & D of supporting of metallocene catalysts, including development of novel carriers, supporting characteristic of the carriers and effects of the supporting on properties of the catalysts and polymerization resultants. It was pointed out emphatically that the studies on the supported metallocene catalysts should be focused on the variation in microenvironment of the catalysts and the corresponding phase structure of the polymers occurred after supporting in order to raise the suitability of the supported metallocene catalysts for the application in the existing commercial plants.更多还原
