ABSTRACT:
A method for bonding homopolymers or copolymers of vinylidene chloride to polyamides which method comprises blending the polymer or copolymer with low density polyethylene, high density polyethylene, linear low density polyethylene, homopolymer or copolymer of propylene, or a copolymer of ethylene and acrylic acid, methacrylic acid and a small amount of copolymer of ethylene and a lower alkyl or hydroxyalkyl ester of acrylic or methacrylic acid and then contacting the blend of polymers with the polyamide under heat and pressure. Unexpected adhesion between the Saran blend and the polyamide was found.
