ABSTRACT:
Thermoplastic blend compositions comprise a polyamide, a carboxylated polyphenylene ether resin and an impact modifier. The carboxylated polyphenylene ether resin is the product of melt mixing a mixture consisting essentially of polyphenylene ether resin and a minor amount of an ethylenically unsaturated carboxylic acid compound. The impact modifier may comprise a graft of a vinyl aromatic polymer on a rubbery substrate; a vinyl aromatic-conjugated diene-vinyl aromatic triblock polymer; a carboxylated vinyl aromatic-conjugated diene-vinyl aromatic triblock polymer; a carboxylated alpha-olefin polymer; a copolymer of an alpha-olefin compound and an unsaturated carboxylic compound; a graft of a rigid acrylic polymer on a rubber substrate; a linear low density polyethylene; or mixtures thereof.
