摘要:
Solid copolymers of butene-1 and 4-vinylcyclohexene prepared by copolymerizing the monomers in the presence of a titanium halide coordination catalyst have an unobvious balance of properties including a broader molecular weight distribution, shorter crystallization half-time, greater isotacticity and greater crystallinity than butene-1 homopolymers prepared with identical catalysts.
