Synthesis and copolymerization of new phosphorus‐containing acrylates

摘要: Two phosphorus-containing acrylate monomers were synthesized from the reaction of ethyl α-chloromethyl and t-butyl α-bromomethyl with triethyl phosphite. The selective hydrolysis ester monomer trimethylsilyl bromide (TMSBr) gave a phosphonic acid monomer. attempted bulk polymerizations at 57–60 °C 2,2′-azobisisobutyronitrile (AIBN) unsuccessful; however, copolymerized methyl methacrylate (MMA) in 60 AIBN. resulting copolymers produced chars on burning, showing potential as flame-retardant materials. Additionally, α-(chloromethyl)acryloyl chloride (CMAC) was reacted diethyl (hydroxymethyl)phosphonate to obtain new identical ether moieties. This hydrolyzed TMSBr, homopolymerized, MMA. thermal stabilities increased increasing amounts phosphonate copolymers. A route highly reactive developed. derivative CMAC mixed groups by substitution, first then sodium acetate. showed highest reactivity crosslinked polymer. incorporation an group rate polymerization. relative reactivities photopolymerizations determined compared those other phosphorous-containing monomers. Changing structure allowed control polymerization so that polymers desirable properties could be obtained. © 2003 Wiley Periodicals, Inc. J Polym Sci Part A: Chem 41: 2207–2217,
