  • Plastic articles with compatibilized barrier resin
    Patent number: 5433984
    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.
    Type: Grant
    Filed: October 13, 1993
    Date of Patent: July 18, 1995
    Assignee: Rohm and Haas Company
    Inventors: Casmir S. Ilenda, Thomas M. Frantz, William T. Freed
