ABSTRACT:
This invention provides an improved adhesive layer for multi-layer films and bottles, the adhesive layer being a graft copolymer of a polyolefin backbone with a methyl methacrylate graft. The graft copolymer sufficiently improves the compatibility between barrier resins and polyolefins to permit the production of monolithic or single layer bottles comprised of a blend of those three components. The resultant products have improved physical properties while retaining acceptable permeability to gases.
