ABSTRACT:
A polyvinyl alcohol alloy useful as a gas barrier material is prepared by reacting polyvinyl alcohol and a functional polymer to provide a product which has low gas permeability and water absorptivity characteristics, and which has a melting point sufficiently below its decomposition point to allow melt extrusion. The alloy may optionally be mixed with a polyolefin blending resin.
