More Information
Summary:A multi-phase polymer composite having reduced oxygen permeability comprising the reaction product of a vinyl thermoplastic polymer having a major portion comprising an interpolymerized non-carbonyl containing vinyl monomer or mixture of polymerizable monomers, a polyhydric polymer derived from a saponified vinyl ester polymer having greater than about 40 mole percent vinyl alcohol content and a reactive coupling agent. The composites exhibit improved impact and delamination resistance and exhibit a wide processing window for melt processing such as injection blow molding of containers and the like.
