Patent ID: 7294663

Claim:
A composition comprising (a) a matrix material of about 50% to 90% by weight of an aromatic polyester; (b) about 5% to 30% by weight of a mineral filler having an equivalent spherical diameter of about 0.05 to less than 4 micrometers and (c) about 10% to 20% by weight of an elastomer comprising thermoplastic polyurethane (TPU); polyether polyester thermoplastic polymers; an ethylene-methyl methyl acrylate (EMA) polymer; an ethylene-butyl acrylate carbon monoxide (EBACO) polymer; an ethylene-vinyl acetate carbon monoxide (EVACO) polymer; or an ethylene-butyl acrylate glycidolmethacrylate polymer (EBAGMA), wherein the weight percentages are based on the total weight of the composition.
