Abstract

Blends of olefin polymers and syndiotactic vinyl polymers are produced by the catalytic polymerization of olefins and aromatic vinyl compounds or methacrylate esters as vinyl compounds in inert diluents in the presence of a catalyst mixture of transition metal compounds, metalloxane compounds and metal alkyl compounds. The blends have a finely dispersed distribution of the blending components and are suitable for the production of films, sheets, fibers, panels, coatings, pipes, hollow objects, injection molded products and foams.
