COMPOSITION AND METHOD FOR IMPROVING ADHESION OF POLYURETHANE FOAM TO SURFACE OF THERMOPLASTIC RESIN BLEND

摘要

PROBLEM TO BE SOLVED: To obtain a composition which can give excellent adhesion between a polyurethane foam and a thermoplastic resin substrate by mixing a thermo plastic resin mixture of a polyphenylene ether with a poly(alkenyl aromatic compound) with an amine-containing substance. SOLUTION: This composition comprises a thermoplastic resin mixture of at least one polyphenylene ether comprising a plurality of structural units desirably of the formula (wherein Q<1> is a halogen, a 1-7C prim. or sec. alkyl, phenyl, a haloalkyl, an aminoalkyl, a hydrocarbonoxy or a halohydrocarbonoxy in which the halogen and the O are separated from each other by at least two carbon atoms; Q<2> is H, a halogen, a prim. or sec. lower alkyl, phenyl, a haloalkyl, a hydrocarbonoxy or a halohydrocarbonoxy as defined in Q<1> ) and at least one prim. amine-containing substance or a sec. amine-containing substance.
