Copolymerizations of N- (4-substituted phenyl) maleimide [N- (4-RP) MI] (M2) with styrene (M1) or methyl methacrylate (M1) by a radical initiator were carried out, and the effects of substituents of N- (4-RP) MI on the copolymerization reaction were investigated. For the relative reactivities of N- (4-RP) MI toward polystyryl radical, no reasonable order was obtained for all substituents. And all of the resulted copolymers were observed to consist of 1: 1 molar composition of N- (4-RP) MI and styrene, independent of themonomer feed ratios in all copolymerization systems. This result will be understood by the fact that in this reaction system the electrostatic interaction between two monomers, styrene and maleimide derivative, is much stronger than the effects by 4-substituent in N- (4-RP) MI.<BR>The differences in relative reactivities (1/r1) of N- (4-RP) MI toward polymethyl methacrylate radical were clearly found. Linear relationships between the log (1/r1) and Hammett's σ values, and also between the e2 values and σ were found.<BR>where ρ=-0.18<BR>Futhermore, we have found a linear relationship between the log 1/r2 and the σ values. This agrees with previous results in the copolymerization system of N- (4-RP) MI (M2) with vinyl acetate (M1). These results might indicate that the radical reactivities of N- (4-RP) MI depend on the polar characters of the 4-substituents.
