METHOD FOR PRODUCING OLEFIN POLYMERS WITH A HIGHER MELTING POINT

摘要

The invention relates to a method for producing polyolefins by polymerizing olefins at pressures ranging from 0.5 to 3,000 bars and at temperatures ranging from -60 to 300 ~C in the presence of a metallocene carrier catalyst. To this end, a metallocene carrier catalyst is used containing the following active constituents: a) a metallocene complex and b) a metallocenium ion forming compound selected from the group consisting of Lewis acids and ionic compounds with non-coordinating anions.
