SynopsisWe have prepared some nitroalkyl acrylates and methacrylates by a method involving alcoholysis, and investigated their polymerizability. 2-Nitrobutyl acrylate (NBA) was extensively studied. The especially purified NBA monomer has good polymerizability without inhibiting radical polymerization and gives a thermally stable polymer. From copolymerization experiments with styrene, methyl methacrylate, and acrylonitrile, the Q and e values of NBA were estimated to be 0.47 and 0.85, respectively. The copolymerization behavior of NBA with some polyglycol dimethacrylates and unsaturated polyesters are comparable to those of n-butyl acrylate. This mqnomer has little tendency to polymerize with organometallic initiators, but some polymers obtained are found to be crystalline. The polar and steric effects of the nitro group situated on the ester side chain are discussed.
