Procedure

In 80 g of propylene glycol monomethyl ether were dissolved 78 g (0.5 mole) of tetrahydropyranyl acrylate and 42 g (0.5 mole) of methyl methacrylate, and 3 g of azobisisobutyronitrile was added thereto, after which they were subjected to polymerization for 10 hours under a nitrogen atmosphere while the reaction temperature was kept at 80° C. After the polymerization, the reaction mixture was dropped into a large amount of water to coagulate a resin. The resin was recovered and dried in a vacuum drier kept at 50° C. overnight to obtain 96 g of a white fine powder of tetrahydropyranyl acrylate/methyl methacrylate copolymer resin.
