Procedure

The reaction was performed under the same reaction conditions and by the same method as in Reference Example 4 using a mixture composed of 99.4 g of tert-butyl methacrylate, 20.0 g of methyl methacrylate, 5.6 g of methacrylic acid (the mole ratio of the above three monomers being 7:2:1), 1 g of benzoyl peroxide and 0.4 ml of n-dodecyl mercaptan. Thus, 102 g of tert-butyl methacrylate-methyl methacrylate-methacrylic acid copolymer (mole ratio 7.0:1.9:1.1) was obtained. Yield 80%. Acid value 46.9. [η]MC25°C. =0.358. The IR characteristic absorptions were the same as those of Reference Example 4.
