Using n-butyl lithium as an initiator and n-hexane as a solvent, 4-vinylpyridine was copolymerized with methylmethacrylate at 0℃ and copolymer composition curve was obtained.
Also the monomer reactivity ratios of this copolymerization system were determined by Fineman-Ross method.
The mechanism of this copolymerization was discussed by these results.
