<p>Thermoplastic compositions and articles made therefrom which have a high receptivity toward automative 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 ethylen-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 automative applications such as bumpers, facias and wheel covers.</p> |
