POLYESTER FILM AND METHODS FOR MAKING SAME

摘要

A polyester film made from a polymer having ethylene glycol moieties, isosorbide moieties and terephthalnoyl moieties, and the method of making the film is described. The polyester film is used to form articles such as films, lacquers, labels, capacitors, insulators, and the like, and has an inherent viscosity of at least 0.35 dL/g when measured as a 1 % (weight/volume) solution of the polyester in o-chlorophenol at a temperature of 25 ~C.
