Sulfonated styrene-maleimide copolymers are similarly active [1073], Examples of maleimide monomers are maleimide, N-phenyl maleimide, N-ethyl maleimide, N-(2-chloropropyl) maleimide, and N-cyclohexyl maleimide. N-aryl and substituted aryl maleimide monomers are preferred. The polymers are obtained by free radical polymerization in solution, in bulk, or by suspension.

The structure of the methyl methacrylate-co-N-cyclohexyl maleimide copolymers is shown in Fig. 33. The maleimide cycle is a rigid structure whose C - C bond contributes to the chain backbone. 

Other functionalized monomers that were polymerized by ATRP are shown in Table HI. Using ATRP, N-vinylpyrrolidone and hydroxypropyl methacrylamide were successfully homopolymerized when a cyclam was used as the ligand instead of bipy. Methyl aciylate and vinyl acetate were copolymerized and a random copolymer with narrow molecular weight distribution was obtained. Copolymerization of isobuter and acrylonitrile monomers was also successful to prepare alternating copolymers. M alternating copolymer was also obtained when styrene and N-(cyclohexyl)maleimide...

The a transition is not included in the considered temperature range. For CMI contents equal to or higher than 10%, two transitions are observed. At low temperatures a shoulder is present, whose extent increases with increasing CMI (y transition). Studies performed on copolymers with maleimide unit N-substituted by isopropyl or phenyl groups [79] do not show this low-temperature transition, which appears to be specific for cyclohexylmaleimide. Such a situation is analogous to the one encountered with poly(cyclohexyl methacrylate) described in Sect. 3. Consequently, this low-temperature transition is assigned to the internal motion of the cyclohexyl ring, i.e. the chair-chair inversion represented in Fig. 7.
