<p>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; and optionally, 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.</p> |
