摘要：A composition, comprising a blend of 10 to 45 weight percent of a polyesterselected from the group consisting of poly(ethylene terephthalate), poly(butyleneterephthalate), poly(1,4-cyclohexyldimethylene cyclohexyl dicarboxylate), or a

combination comprising at least one of the foregoing; and 55 to 90 weight percent of apoly(ester-ether)copolymer, each based on the total weight of the polyester and thepoly(ester-ether)copolymer; wherein the poly(ester-ether)copolymer comprises unitsderived from terephthalic or a chemical equivalent thereof, units derived from butanediol or a chemical equivalent thereof, and 25 to 65 weight percent of units derived frompoly(oxytetramethylene)glycol or a chemical equivalent thereof, based on the weight ofthe copolymer; wherein the composition retains at least 50% of at least one of tensilestrength, modulus, stress at maximum strain, or the elongation at break is larger than150% after being exposed to a temperature of 140° C. for 70 hours, as measured byASTM D-638.
