Методика

With the use of 48.6 g (0.30 mole) of p-acetyloxystyrene, 17.6 g (0.10 mole) of p-tert-butoxystyrene and a catalytic amount of 2,2′-azobis(2,4-dimethylvaleronitrile), the same reaction and after-treatment as described in Production Example 2-(1) were conducted, and the resulting viscous resinous material was dissolved in 200 ml of acetone and poured into 1000 ml of 50% aqueous methanol solution. The precipitated resin was recovered by decantation and dried under reduced pressure to give 59.7 g of poly(p-acetyloxystyrene/p-tert-butoxystyrene) as white powders. A ratio of p-acetyloxystyrene unit and p-tert-butoxystyrene unit was about 3:1 by 1HNMR. Mw: about 10500, Mw/Mn: 1.32 (GPC method: polystyrene as standard).
