Abstract
An amorphous copolyester having a maximum melt viscosity at 1 radian/second and at about 260 to about 290° C. of about 12000 poise, a glass transition temperature ranging from about 88° C. to about 120° C., and an inherent viscosity of at least about 0.6 dl/g. The amorphous copolyesters comprise the reaction product of a diol component and a dicarboxylic acid component. The diol component comprises residues of from about 5.0 to about 50 mole % of 2,2′-(sulfonylbis (4,1-phenyleneoxy))-bis(ethanol) which has the following chemical formula:
