ABSTRACT:
Disclosed are polyesters comprised primarily of residues of 4,4'-biphenyldicarboxylic acid, ethylene glycol and 1,4-butanediol. Articles injection-molded from the polyesters exhibit a unique combination of properties including unusually high tensile strength and excellent heat resistance, flexural modulus and resistance to chemicals and solvents.
