摘要：

The radical copolymerization of N-vinyl-tert-butylcarbamate (NVTBC) with styrene, methyl methacrylate, vinyl-pyrrolidone and 4-vinyl-pyridine was studied at 50-60° C in toluene, methanol or dioxane, using azo- bis- isobutyronitrile as the initiator. The reactivity ratios of the monomers were calculated from monomer feed and copolymers composition data using the Fineman-Ross method. The copolymers were hydrolysed in CH3COOH/HCl mixtures at room temperature in order to obtain vinylamine containing copolymers. The extent of the solvolysis is dependent on the nature of the comonomer. The solvolysed copolymers bearing NH2 groups were titrated by HCl in 2M NaCl medium in order to have more informations on the repartition of the NVTBC residues. © 1990 Springer-Verlag.
