Sulfur-based copolymers are fascinating materials with a wide range of applications. This review
article delves into the synthetic aspects of sulfur copolymers, their characteristics, and their
applications. Sulfur is a byproduct of refineries, produced in large quantities worldwide. Various
sulfur-based copolymers have been synthesized through inverse vulcanization, catalyst-induced low temperature inverse vulcanization, and polycondensation reactions. Researchers have studied a variety
of monomers, including benzoxazine moieties and sulfur-based systems with allylic or vinylic
functionalities. The article discusses the characterization of sulfur copolymers, such as sulfur
quantification in copolymers, solubility, microstructure, molecular weight, processability, and selfhealing
properties. Further, it highlights the current challenges associated with large-scale
applications of sulfur-based copolymers. Applications discussed include Li-S batteries, IR transparent
lenses, concrete, controlled-release fertilizers, removal of toxic metals from water, biomedical
applications, and environmental remediation.
