Claim 13:
14. A mobile electronic device component comprising a polyester composition comprising:
from about 20 wt. % to no more than about 80 wt. % of a semi-aromatic, semi-crystalline polyester polymer, relative to the total weight of the polyester composition;
from about 1 wt. % to about 40 wt. % of a reactive impact modifier comprising acrylic ester moieties and glycidyl methacrylate moieties, relative to the total weight of the polyester composition; and
from about 15 wt. % to about 50 wt. % of an amorphous polyester polymer or a combination of an amorphous polyester polymer and an amorphous polycarbonate polymer, relative to the total weight of the polyester composition;
wherein the amorphous polyester is a copolyester comprising recurring units (Rpe1) and (Rpe2):
wherein:
recurring unit (Rpe1) is represented by the formula -[-Ma-Mb-]-
recurring unit (Rpe2) is represented by the formula -[-Ma-Mc-]-

R9, R10, R11, R12, R13 and R14 , at each instance, is independently selected from the group consisting of a halogen, an alkyl, an alkenyl, an alkynyl, an aryl, an ether, a thioether, a carboxylic acid, an ester, an amide, an imide, an alkali or alkaline earth metal sulfonate, an alkyl sulfonate, an alkali or alkaline earth metal phosphonate, an alkyl phosphonate, an amine, a quaternary ammonium, and any combination thereof;
t″ is an integer from 0 to 6;
u″ is an integer from 0 to 10;
t, t′, u and u′ are, at each instance, an independently selected integers ranging from 0 to 2; and
x, x′, y and y′ are independently selected integers ranging from 0 to 20.
