80 °C

9.0 g of methyl methacrylate, 0.86 g of methacrylic acid (charging ratio by mole=9/1), and 50 mg of benzoyl peroxide were dissolved in 50 g of dioxane, followed by heating the solution at 80° C. for 4 hours with agitation while purging with nitrogen and subsequently charging into a large amount of water. The resulting polymer was dissolved in a small amount of acetone and dropped into a large amount of a methanol/water mixture for re-precipitation, followed by drying in vacuo to obtain methyl methacrylate/methacrylic acid copolymer (molecular weight≈5,000).
