ABSTRACT:
A copolymer of trans-1,4-hexadiene and propylene, and a method for its preparation. The copolymer is isotactic, essentially free of cis-1,4-hexadiene, and contains from 0.01 to 5 mole percent 1,4-hexadiene. The copolymer is radiation-stabilized against molecular weight degradation, and cross-links to form gel upon exposure to radiation. The copolymer is prepared by contacting a mixture of propylene and 1,4-hexadiene essentially free of cis-1,4-hexadiene with a coordination catlyst, e.g. Ziegler-Natta catalyst, under copolymerization conditions. Hydrogen is used to moderate the molecular weight of the copolymer and enhance the catalyst activity.
