Homopolymerizations and copolymerizations of N-phenylcitraconimide (I), N-benzylcitraconimide (II), N-n-hexylcitraconimide (III), N-n-butylcitraconimide (IV), and N-i-propylcitraconimide (V) were carried out at 60℃ by using azobisisobutyronitrile as an initiator in tetrahydrofuran. The conversion for homopolymerizations of N-substituted citraconimides at 60℃ for 3∿6 hrs was less than 5%. The reactivity ratios were determined as r_1=0.004,r_2=0.18; r_1=0.059,r_2=0.24; r_1=0.017,r_2=0.43; r_1=0.048,r_2=0.19; r_1=0.056,r_2=0.31 for the copolymerizations of I, II, III, IV, and V (M_1) with styrene (M_2), respectively. The Q and e values calculated from these reactivity ratios were Q=0.65,e=1.89 for I; Q=0.79,e=1.26 for II; Q=0.40,e=1.42 for III; Q=0.94,e=1.37 for IV; and Q=0.66,e=1.20 for V.
