摘要：
Described are polyesters containing (a) a dicarboxylic acid component having from 70 to 100 mole % of terephthalic acid residues, and up to 30 mole% of aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues; and (b) a glycol component having from 40 to 65 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues, and from 35 to 60 mole % of cyclohexanedimethanol residues; wherein the total mole % of the dicarboxylic acid component is 100 mole %, and the total mole % of the glycol component is 100 mole %. The polyesters may be manufactured into articles such as fibers, films, containers, bottles or sheets.
