Hydrodynamic Parameters of Linear Aromatic Polyester of 3-Phenylglutaric Acid and Bisphenol A

Abstract

A series of samples of linear aromatic polyester of 3-phenylglutaric acid and bisphenol A was prepared with molecular weights ranging from 14 700 to 92 700. The polymers were characterized by size exclusion chromatography with triple lightscattering, viscosity, and concentration detection. Hydrodynamic parameters of the chain were determined using the theory of Yoshizaki, Yamakawa, and Nitta modified by Bohdanecký and Netopilík. The chain parameters are a useful reference in the study of aromatic hyperbranched polyesters.
