The copolymerization of NVIM with different donor–acceptor
monomers, such as styrene, 4-aminostyrene, vinyl acetate, Nvinyl-
2-pyrrolidone, maleic anhydride, methyl acrylate, acrylonitrile,
methyl methacrylate, dialkyl fumarates, ethyl acrylate and
the determination of the monomer reactivity ratios have been also
reported [9–15]. It was shown that these imidazole-containing
copolymers obtained from a wide range of monomer feeds had different
compositions, which vary from random to alternating
structures.
