ABSTRACT:
A resin composition for improving adhesion with polyurethane foam is disclosed which comprises:(a) about 10 to about 80 percent by weight of at least one polyphenylene ether resin;(b) about 20 to about 70 percent by weight of at least one polyolefin polymer;(c) about 1 to about 20 percent by weight of at least one amine compound; and(d) 0 to about 4 percent by weight of at least one adhesion promoter, wherein all percentages are based on the weight of the entire composition.In preferred embodiments, the resin composition further comprises at least one member of the group consisting of polyphenylene ether-polyolefin copolymers, polystyrene-polyolefin copolymers, and polystyrene resins. Also disclosed herein is a method for improving adhesion between a resin composition and polyurethane foam.
