Polyesters containing sulfur. I. Products of melt polycondensation of diphenylmethane‐4,4′‐di(methylthioacetic acid) with some diols

摘要

AbstractSeveral new polyesters containing sulfur in the main chain were obtained by melt polycondensation of diphenylmethane‐4,4′‐di(methylthioacetic acid) with ethanediol, 1,3‐propane diol, 1,4‐butanediol, 1,5‐pentenediol, 1,6‐hexanediol, 1,2‐propanediol, and 2,2′‐oxydiethanol. The structure of all polyesters was determined from elemental analysis and infrared (IR) spectra. Yield, reduced viscosity, molecular weight, and softening temperature for reaction products have been found. Initial decomposition and initial intensive decomposition temperature were defined from the curves of thermog
