✦ Synopsis
The copolymerization of maleic anhydride (MA), N-2-chlorophenyl maleimide (2-CMI) and N-a-naphthyl maleimide (a-NMI) with styrene (ST) initiated by y-radiation has been studied. The initial rate of copolymerization depends on the total concentration of the comonomers, and the rate decreases in the series ST/MA > ST/a-NMI > ST/2-CMI. The maximum rate occurred at a ratio for which [M,] > [ST]. The rate of formation and the reaction of mi is greater than m i . The monomer reactivity ratios indicate that t h e ratio of alternating units decreases in the order ST/MA > ST/a-NMI > ST/2-CMI.
