Methyl Methacrylate → Diethyl carbonate ethylene carbonate

Participants

Reaction Conditions

Reaction Steps

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 of N,N′-azobisisobutyronitrile were placed in a three-necked flask equipped with a reflux condenser, and mixed for 30 minutes under stirring while introducing nitrogen gas. Temperature was elevated to 70° C. to conduct radical polymerization for 8 hours. The reaction mixture thus obtained was cooled to 40° C. 226.6 g of diethyl carbonate and 0.15 g of N,N′-azobisisobutyronitrile were added to the reaction mixture, and the resulting mixture was again heated to 70° C. to further conduct radical polymerization for 8 hours. The reaction mixture thus obtained was cooled to 40° C. to obtain an ethylene carbonate/diethyl carbonate mixed solvent solution (concentration: 15% by weight) of the crosslinkable polymer B.
