Abstract
Polyester compositions which contain a copolymer of ethylene, an acrylate ester, and a fibrous filler having a relatively small diameter are particularly suitable for parts whose surface appearance is important, such as appliance panels and automobile body panels. The compositions have good toughness and an otherwise excellent balance of other physical properties.
Claims15
A composition, comprising:
- (a) about 1.0 to about 40 percent by weight of a copolymer consisting essentially of repeat units derived from ethylene, and a compound of the formula H2C═CHCO2R1 (I), wherein R1 is an alkyl group containing 1 to 8 carbon atoms, and said ethylene-derived repeat units are about 65 to about 95 weight percent of said copolymer, and said (I)-derived repeat units are about 5 to about 35 weight percent of said copolymer;
- (b) about 35 to about 90 percent by weight of a semicrystalline polyester;
- and
- (c) about 5 to about 30 percent by weight of short fibers having a number average diameter of about 6 μm or less;
- wherein the parts by weight are based on the total amount of (a), (b) and (c) present.
2 more elements
