Abstract

Abstract : The accelerator effect of amine activators N ‐methylimidazole and 4‐vinylaniline (4‐VA) on inverse vulcanization and dynamic covalent polymerization (DCP) has been investigated. The sulfur polymer with self‐activation comonomer 4‐VA could also be used for low temperature DCP to incorporate some volatile monomers. Those approaches provide a new synthetic and rate accelerated processes to activate S8 for copolymerization processes with functional comonomers at lower temperatures and under a broader range of reaction conditions.
