Abstract
A thermoplastic molding composition comprising a polyester blend of polybutylene terephthalate and a copolyester derived from condensing ethylene glycol, cyclohexanedimethanol and terephthalic acid wherein the ethylene glycol units of the copolyester comprises at least 25 mole % based on the total glycol content. The polyester blend can also include an impact modifier. The blend is useful in the formation of molded keycaps.
