Poly(alkyl vinyl ether)polyolefin copolymers

A blend of a polyolefin and a poly(alkyl vinyl ether) can be blended at elevated temperature to form a copolymer of the polyolefin and poly(alkyl vinyl ether). The resulting composition is useful as a compatibilizer, as a more water permeable substrate than the polyolefin, and as a photo-degradable material.
