Abstract:
1. An amorphous copolyester having an inherent viscosity (IV) of at least about 0.5 dL/g measured at a temperature of 25° C. at 0.5 g/dL concentration in a solvent mixture of symmetric tetrachloroethane and phenol having a weight ratio of symmetric tetrachloroethane to phenol of 2:3 comprising: (1) a diacid component comprising about 90 to 100 mole percent terephthalic acid residues and 0 to about 10 mole percent isophthalic acid residues; and (2) a diol component comprising about 10 to about 70 mole percent 1,4-cyclohexanedimethanol residues and about 90 to about 30 mole percent neopentyl glycol residues; wherein the amorphous copolyesters comprises 100 mole percent diacid component and 100 mole percent diol component.
