Advances and opportunities in synthesis of flame retardant polymers via reversible deactivation radical polymerization

Looking for innovative, more efficient and cost-effective synthesis methods of flame retardants (FRs) polymers is arousing increasing interest in the research community. The main aim is to develop human and environmentally safe flame retardants using renewable resources. Consequently, hazardous halogen flame retardants are being replaced by phosphorus, nitrogen and polymer/inorganic nanocomposite flame retardants. In view of the growing consumption of plastics as well as natural materials, here is an increasing demand for specific flame retardants and innovative and at the same time environmentally friendly methods of their synthesis. Reversibledeactivation radical polymerization (RDRP) techniques might be a breakthrough tool for the precise synthesis of FRs. Such techniques provide an opportunity to synthesize polymers with complex architectures, defined molecular weight and low dispersity (sic) both in solution and grafted directly from modified materials. Therefore, this review summarizes the use of RDRP techniques of various monomers over the past 10 years for the synthesis of flame retardant additives as well as for direct surface modification towards reducing flammability.
