Crosslinker copolymerization for property control in inverse vulcanization

Sulfur is an underused by-product of the petrochemicals industry. Recent research into inverse vulcanisation has shown how this excess sulfur can be transformed into functional polymers, by stabilization with organic crosslinkers. For these interesting new materials to realise their potential for applications, more understanding and control of their physical properties is needed. Here we report four new terpolymers prepared from sulfur and two distinct alkene monomers that can be predictively tuned in glass transition, molecular weight, solubility, mechanical properties, and colour.
