Abstract
A composition, comprising a blend of 10 to 45 weight percent of a polyester selected from the group consisting of poly(ethylene terephthalate), poly(butylene terephthalate), poly(1,4-cyclohexyldimethylene cyclohexyl dicarboxylate), or a combination comprising at least one of the foregoing; and 55 to 90 weight percent of a poly(ester-ether)copolymer, each based on the total weight of the polyester and the poly(ester-ether)copolymer; wherein the poly(ester-ether)copolymer comprises units derived from terephthalic or a chemical equivalent thereof, units derived from butane diol or a chemical equivalent thereof, and 25 to 65 weight percent of units derived from poly(oxytetramethylene)glycol or a chemical equivalent thereof, based on the weight of the copolymer; wherein the composition retains at least 50% of at least one of tensile strength, modulus, stress at maximum strain, or the elongation at break is larger than 150% after being exposed to a temperature of 140° C. for 70 hours, as measured by ASTM D-638.
