摘要: Crosslinking of diene rubbers by the traditional sulfur-based curing package inevitably utilizes toxic activators and accelerants, which causes potential dangers environmental pollution. Herein, we report on rapid synthesis sulfur co-polymers inverse vulcanization S8 styrene through a nucleophilic activation mechanism demonstrate that vulcanised co-polymer is highly efficient in crosslinking green manner. Compared with sulfur-cured counterpart, co-polymer-cured sample an identical density exhibits remarkably larger breaking strain higher elasticity.
