Abstract

Abstract: In this concept review, the fundamental and polymerization chemistry of inverse vulcanization for the preparation of statistical and segmented sulfur copolymers, which have been actively developed and advanced in various applications over the past decade is discussed. This concept review delves into a discussion of step‐growth polymerization constructs to describe the inverse vulcanization process and discuss prepolymer approaches for the synthesis of segmented sulfur polyurethanes. Furthermore, this concept review discusses the advantages of inverse vulcanization in conjunction with dynamic covalent polymerization and post‐polymerization modifications to prepare segmented block copolymers with enhanced thermomechanical and flame retardant properties of these materials. Abstract : The detailed discussion of the fundamental and polymerization mechanism for sulfur copolymers is described from ring‐opening polymerization, inverse vulcanization, dynamic covalent polymerization. In this article, we highlight the segmented sulfur polyurethane with flame retardancy through post‐polymerization of sulfur copolymers. And we give the prospects for various applications of sulfur derived polymers.
