Document Type and Number:

Japanese Patent JP2974404

Kind Code:

B2

Abstract:

There is disclosed a homoplymer of an alkenylsilane having a syndiotactic structure and a copolymer of the alkenylsilane and an alpha -olefin. The polymer and the copolymer can be prepared by subjecting the alkenylsilane or the alkenylsilane and the alpha -olefin to addition polymerization in the presence of a transition metal compound having asymmetirically interconnected ligands or preferably in the presence of the transition metal compound and aluminoxane. The polymer and the copolymer can be used as a nucleating agent for a crystalline polypropylene.
