Synthesis, characterization, degradation and applications of vinyl polyperoxides

Abstract

Polymeric peroxide is an equimolar alternating copolymer formed by the reaction of a monomer with molecular oxygen (O2). Various polyperoxides have been successfully synthesized using different techniques, such as free radical polymerization, condensation polymerization, and insertion polymerization in the solid state. A wide variety of physical and chemical characteristics are displayed by these polyperoxides, making them attractive candidates for various applications. Due to their high exothermal degrading behavior and autocombustibility, polyperoxides are a viable alternative to fuels derived from petroleum. Additionally, polyperoxides have a wide range of applications, such as free radical initiators, curatives, biocompatible drug carriers, coating materials, dismantlable adhesives, and molding precursors. In this focused review, we report on recent efforts in developing vinyl homo- and copolyperoxides, their physicochemical behaviors, and various applications. Finally, the existing opportunities, possible challenges, and some viewpoints on future directions in vinyl polyperoxide research are highlighted. Our recent studies on the synthesis, characterization, degradation and applications of vinyl polyperoxides are reviewed. Primarily, the recent achievements in the design, biocompatibility, thermal and enzymatic degradation of water-soluble vinyl polyperoxides and copolyperoxides are described. Finally, future development possibilities and challenges of vinyl polyperoxides for various potential applications are summarised.
