| 摘 要： | The effects of solvent polarity on free radical copolymerization of 5-hexenoie acid and acrylonitrile at 60℃ were studied. It was observed thatas the polarity of solvents enhanced, both the copolymcrization rate and the reactivity ratios r_1, r_2 increased, while the alternating tendency of monomer units in copolymer chain decreased. It is believed that the solvent polarity raises the reactivities of acrylonitrile monomer and its growing chain radical, but causes no distinct variation in those of 5-hexenoic acid.
