POLYESTER COMPOSITIONS CONTAINING CYCLOBUTANEDIOL HAVING A CERTAIN COMBINATION OF INHERENT VISCOSITY AND MODERATE GLASS TRANSITION TEMPERATURE AND ARTICLES MADE THEREFROM

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 1,4-cyclohexanedimethanol residues. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.
