摘要：

The preparation and vibrational spectroscopic characterization of the hitherto unreported products of the copolymerization of 2,3-dimethylbutadiene and methyl methacrylate are presented. The polymers were prepared by free radical polymerization using alpha,alpha'-azobisisobutyronitrile as the initiator. Raman and Fourier transform infrared spectroscopic information on the 2,3-dimethylbutadiene-methyl methacrylate copolymer is presented for a range of copolymers differing in the 2,3-dimethylbutadiene to methyl methacrylate ratio. Quantitative information of the microstructure of the polymer and copolymer using the C=C stretching vibrations is provided by Raman spectroscopy. Evidence is presented for the splitting of the C=O stretching vibration, ascribed to aggregated syndiotactic and unaggregated syndio- and isotactic poly(methyl methacrylate) at 1734 and 1724 cm-1, respectively.
