New polyester-sulfur compositions with increased tensile strength were obtained by using new thiopolyesters crosslinkable with sulfur, derived from diphenylmethane-4,4-di(methylthiopropionic acid) and ethanediol (E-P) or 2,2-oxydiethanol (ODE-P). Such characteristics as hardness, tensile, thermomech

Abstract
New polyester–sulfur compositions with increased tensile strength were obtained by heating polyesters derived from diphenylmethane‐4,4′‐di(methylthioacetic acid) and ethylene or diethylene glycol with elemental sulfur. The hardness, tensile, thermomechanical, as well as some electrical properties of reaction products were determined. © 1993 John Wiley & Sons, Inc.
