• Homopolymerizations and copolymerizations of N-phenyl itaconimide (PhII), N-(4-chlorophenyl) itaconimide (ClPhII), N-(4-methylphenyl) itaconimide (MPhII), and N-1-naphthyl itaconimide (NII) were carried out at 60℃ by using azobisisobutyronitrile (AIBN) as an initiator in tetrahydrofuran. The initial rates of the polymerization were R_p=k[AIBN]^<0.6>[PhII]^<1.5>, R_p=k[AIBN]^<0.5>[ClPhII]^<1.1>, R_p=k[AIBN]^<0.5>[MPhII]^<1.0>, and R_p=k[AIBN]^<0.5>[NII]^<1.0>, where k is rate constant. The over-all activation energies (E) and frequency factors (A) were E=19.5 kcal/mol (PhII), 16.1 kcal/mol (ClPhII), 20.1 kcal/mol (MPhII), 17.5 kcal/mol (NII) and A=9.9×10^9 (PhII), 3.1×10^7 (ClPhII), 1.7×10^<10> (MPhII), 4.5×10^8 (NII). The reactivity ratios were determined as r_1=0.08, r_2=0.05; r_1=0.14, r_2=0.15; r_1=0.24, r_2=0.16; r_1=0.35, r_2=0.08 for the copolymerizations of PhII, ClPhII, MPhII and NII (M_1) with styrene (M_2), respectively. The Q and e values calculated from these reactivity ratios were Q=1.9, e=1.6 for PhII; Q=1.4, e=1.2 for ClPhII; Q=1.5, e=1.0 for MPhII; and Q=2.7, e=1.1 for NII.
