Abstract: A compatibilizing agent for polymeric blends of polycarbonates and polyamides which have improved physical and chemical resistance properties, without any substantial sacrifice of the desirable properties of the polycarbonate or polyamide.

Abstract: Thermoplastic compositions and articles made therefrom which have a high receptivity toward automotive paints comprises the following components:2%-25% of a copolymer of an ethylenically unsaturated carboxylic acid and ethylene,3%-50% of an elastomer comprising an ethylene-alpha-olefin copolymer,1%-50% of a crystalline homopolymer or copolymer of propylene,5%-40% of polyethylene or a copolymer of ethylene and an alpha-olefin,2%-20% of an epoxy or phenoxy resin; andoptionally, up to 50% of an inorganic filler. Such articles, when injection molded, exhibit flexural moduli in the range of 100,000 to 200,000 psi and have excellent paintability, a broad range of stiffness values and high impact and tensile strengths suitable for automotive applications such as bumpers, facias and wheel covers.
