실험 절차

By the same method and under the same reaction conditions as in Reference Example 4, the dispersing medium was changed from kerosene to ISOPAR-E (an alkane-type solvent, made by Esso Corporation, U.S.A.), and 78.5 g of iso-butyl methacrylate, 15 g of methyl methacrylate, 5.6 g of methacrylic acid (the mole ratio of the three monomers being 5.5:1.5:3), 1 g of benzoyl peroxide and 1 ml of n-dodecyl mercaptan were reacted in 350 ml of the dispersing medium to afford 107 g of iso-butyl methacrylate-methyl methacrylate-methacrylic acid copolymer. Yield 90%. Acid value 169.6. [η]MC25°C. =0.232.
