Versuchsvorschrift

In a 500 ml round-bottom flask was placed 0.3 mole of 2-(toluene-4-sulfonyloxy)ethyl methacrylate, 0.25 mole of 2-hydroxyethyl acrylate, 0.15 mole of methyl methacrylate, 0.3 mole of glycidyl methacrylate, 300 g of tetrahydrofuran (THF), and 0.1 g-3 g of 2,2-azobisisobutyronitrile (AIBN). The reaction mixture was heated at 60-75° C. for 5-20 hours. The product was precipitated in ethyl ether or n-hexan, filtered and dried to provide poly [2-(toluene-4-sulfonyloxy)ethyl methacrylate/2-hydroxyethyl acrylate/-methyl methacrylate/-glycidyl methacrylate] represented by the following chemical formula 10, at a yield of 65-70%.
