ABSTRACT:
A catalyst component for olefin polymerization is a mixture of a transition metal composition with finely divided talc or a metal salt of an aromatic carboxylic acid. The talc or metal salt can be mixed with the transition metal composition during the production thereof or in a subsequent stage. Preferably an intimate mixture of the transition metal composition and the talc or metal salt is obtained, for example by grinding or by spraydrying. The catalyst component may be used to prepare an olefin polymer having improved properties.
