Reaction Conditions

Reaction Steps

Into a reactor were introduced 210 ml of methyl ethyl ketone, 6.9 g of 2-hydroxyethyl methacrylate, 1.9 g of acrylic acid and 21.2 g of ethyl methacrylate. After purging the reactor with nitrogen, the mixture was heated to 75° C. Next, a solution of 3.0 g of dimethyl-2,2'-azobisisobutyrate in 20 ml of methyl ethyl ketone was added thereto and the polymerization was initiated. A monomer solution consisting of 62.1 g of 2-hydroxyethyl methacrylate, 17.2 g of acrylic acid and 190.7 g of ethyl methacrylate and an initiator solution of 3.0 g of dimethyl-2,2'-azobisisobutyrate in 50 ml of methyl ethyl ketone were dropped into the container each over 6 hours. After the completion of the addition, 3.0 g of dimethyl-2,2'-azobisisobutyrate dissolved in 20 ml of methyl ethyl ketone was further added and the resultant mixture was heated and stirred for 4 hours to give a colorless, transparent and viscous liquid reaction mixture. The liquid reaction mixture was cooled to room temperature and then 245 ml of methyl ethyl ketone was added thereto to lower the viscosity to give 706 g of a copolymer solution having a solid content of 42.9% (polymer yield: 98.0%).
