Vorschrift

60.0 g of methyl methacrylate, 16.0 g of 3-ethyl-3-oxetanylmethyl methacrylate, 4.0 g of 3,4-epoxycyclohexylmethyl acrylate, 226.6 g of ethylene carbonate and 0.15 g 2,2′-azobis(isobutyronitrile) were placed in a 500 mL capacity three-necked flask equipped with a refluxing condenser and stirred and mixed for 30 minutes while nitrogen gas was introduced into the flask. Then the resulting mixture was heated to 70° C. and radical polymerization was carried out over 8 hours at the temperature. The resulting reaction mixture was cooled to 40° C. 226.6 g of diethyl carbonate and 0.15 g of 2,2′-azobis(isobutyronitrile) were added to the reaction mixture and the resulting mixture was again heated to 70° C. to carry out radical polymerization at the temperature for another 8 hours. Then the resulting reaction mixture was cooled to 40° C. to obtain a solution of a polymer in a concentration of 15% by weight in a solvent of ethylene carbonate/diethyl carbonate mixture.
