Phosphorus-Containing Acrylate-Based Core-Shell Polymers: Synthesis and Flame-Retardant Properties.

ABSTRACT: To address the flammability issues limiting polymer applications, phosphorus-containing flame retardants have received increasing attention as halogen-free alternatives. In this study, two phosphorus-containing methacrylate monomers, diphenylphosphinyl methacrylate (DPMA, +1 oxidation state, P-Ph bond) and diphenylphosphoryloxy methacrylate (DPOMA, +5 oxidation state, P-O-C bond), were synthesized and selectively incorporated into the shell of core-shell polymers via seeded emulsion polymerization. The resulting particles were uniform, spherical, and low polydispersity (PDI < 0.07). The flame-retardant behavior was strongly affected by the oxidation state of phosphorus. When 70 wt % of each monomer was placed in the shell, PA-DPMA70 reduced the peak heat release rate (
