ABSTRACT:
Disclosed are orientable, heat setable, semi-crystalline copolyesters which have high glass transition temperatures. These copolyesters have high heat distortion temperatures along with excellent molding and film properties which makes them useful in packaging materials and molded parts. These copolyesters have repeat units from about 100 mol % 1,4-cyclohexanedimethanol, about 1-99 mol % terephthalic acid and about 99-1 mol % naphthalene dicarboxylic acid.
