Synthesis and Polymerization of a New Acrylic Monomer Containing Bicycloheptenone Moiety
A new acrylic monomer containing tetraphenyl-substituted bicycloheptenone moiety was prepared through the designed reaction scheme. The reaction intermediates obtained during the series of reaction were identified. The final product of white solid monomer (mp. 202-204 ℃, MW:593.7) was homopolymerized and copolymerized with methyl methacrylate (MMA) in N,N-dimethylformamide (DMF) by using a radical initiator, 2,2''-azobisisobutyronitrile (AIBN). The copolymer reactivity ratios of the monomer and MMA at high conversions were found to be 0.31 and 1.06, respectively, according to the calculation of Kelen-Tudos method. UV, NMR and elemental analysis were employed to determine the composition of the copolymer. The results from each method were close within an experimental error range
