POLYESTER COMPOSITIONS CONTAINING CYCLOBUTANEDIOL HAVING A CERTAIN COMBINATION OF INHERENT VISCOSITY AND HIGH GLASS TRANSITION TEMPERATURE AND ARTICLES MADE THEREFORM.

摘要

Described are polyester compositions comprising at least one polyester which comprises terephthalic acid residues, 2,2 ,4,4-tetramethyl-1 ,3- cyclobutanediol, and 1 ,4-cyclohexanedimethanol, wherein the inherent viscosity and the Tg of the polyester provides for certain polyester properties. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.
