Preparation of spirobiindane polyarylates, and spirobiindane polyarylate- polyethylene terephthalate copolymers, via melt polymerization

摘要

The preparation of spirobiindane polyarylate compositions having reduced cyclic oligomer formation and glass transition temperature which can be varied depending upon the percent composition of linear diacids and linear dihydric phenols present therein. Spirobiindane polyarylate- polyester copolymers and methods for their preparation are also disclosed.
