摘要：
Described are polyesters comprising (a) a dicarboxylic acid component comprising terephthalic acid residues; optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues; 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and cyclohexanedimethanol residues. The polyesters have a desirable combination of inherent viscosity and glass transition temperature (“Tg”). The polyesters can have an inherent viscosity from 0.35 to 1.2 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.5 g/100 ml at 25° C. and a Tg of 85 to 115° C. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.
