摘要

AbstractNew polyesters were obtained by interfacial polycondensation ofbis(4‐hydroxyphenyl)ether with succinyl, adipolyl, suberoyl, or sebacoyl chlorides. To define the optimal conditions of the process, the polyesters of diol and adipoyl or sebacoyl chlorides were chosen as a model system. Yield for all reaction products and reduced viscosity were found. The following factors were studied: organic phase, contribution of catalyst, concentration and molar ratio of reagents, rate of addition of acid chloride, temperature of reaction and concentration of hydrochloride acceptor. The structure of all polyesters was determined by means of elementary analysis, infrared spectra, and X‐ray. Initial decomposition and initial intensive decomposition temperatures were defined by the curves of thermogravimetric analysis. Thermal and electrical properties of polyesters from diol and adipoyl or sebacoyl chlorides were studied. The molecular weights for these polymers were also determined by gel chromatogra
