Three maleimide derivatives which were characterized by the presence of hydroxyl radical in N-substituent, i. e. N-4-Hydroxyphenyl maleimide (HPMI), N-2-Hydroxyethyl maleimide (HEMI) and N-Methylol maleimide (MMI) were synthesized. Their polymerizations, 1) initiated with potassium persulphate in water or water-dioxane mixture solution, 2) initiated with azobisisobutyronitrile in dimethylformamide solution, and 3) initiated with n-butyllithium in tetrahydrofuran solution were studied. In 1), the relatively low conversion and the presence of maximum conversion in the polymerization curve were ascribed to the properties of initiator. In 2) the square root law of the polymerization did not hold for any monomer. The rate of polymerization of HPMI was the highest but the reduced viscosity of the polymer decreased with increase in the conversion. These phenomena were explained by the high activity of hydroxyl group in HPMI monomer. In 3) some oligomers containing a trace of lithium were obtained and it was ascertained that the hydroxyl group in the monomers did not entirely stop the anionic polymerization. The acetalizing reaction of HEMI polymer with formaldehyde and the adsorption of iodine by the acetalized polymer were briefly examined.
