Abstract
2,2-Dimethyl-3-oxobutyl methacrylate (DMBM) was synthesized from 4-hydroxy-3,3-dimethyl-2-butanone and methacrylic acid. The polymerization of DMBM was carried out in benzene at 60°C, using 2,2′-azobisisobutyronitrile (AIBN) as an initiator. The rate equation was found to be usual: Rp=k[AIBN]0.58 [DMBM]0.98. The polymerization parameters (Ea, kp/kd1/2, 2fkd, Cm, and Cs) were also determined. From the copolymerization with styrene, the reactivity ratios, Q and e of DMBM were obtained. It is also proposed that the values of Q and e of any vinyl monomers could be calculated from the λmax value of the UV spectrum and the chemical shift of the β-carbon atom of the vinyl group in the 13C-NMR spectrum of the monomer.
