Abstract (en)
[origin: WO8807564A1] Thermoplastic compositions and articles made therefor which have a high receptivity toward automotive paints comprises components (a), (b), (c), (d) and (e), wherein, for example, 2 %-25 % (a) is a copolymer of an ethylenically unsaturated carboxylic acid and ethylene, 3 %-50 % (b) is an elastomer comprising an ethylene-alpha-olefin copolymer, 0 %-55 % (c) is a crystalline homopolymer or copolymer of propylene, 5 %-50 % (d) is an inorganic filler, and 10 %-35 % (e) is polyethylene or a copolymer of ethylene and an alpha-olefin. Such articles, when injection molded, exhibit flexural moduli in the range of 30,000 to 400,000 psi and have excellent paintability, a broad range of stiffness values and high impact and tensile strengths suitable for automotive applications such as bumpers and facias and wheel covers.
