Abstract:
A compatible semicrystalline polyolefin alloy comprising two homopolymers A.sub.n and B.sub.m having dissimilar stereoisomeric or dissimilar geometric isomeric structure and a block copolymer of the formula (A.sub.a B.sub.b).sub.x where n and m are large integers from 1,000 to 30,000, a and b are smaller integers from 100 to 3,000, x is an integer from 1 to 100, wherein the polyolefin alloy has a weight ratio of A.sub.n and B.sub.m between 100:1 and 1:100, and the block copolymer (A.sub.a B.sub.b).sub.x is between 2% and 20% by weight.
