Procedure

In a 500 ml round-bottom flask was placed 0.3 mole of 2-(toluene-4-sulfonyloxy)ethyl acrylate, 0.33 mole of 3-hydroxypropyl acrylate, 0.22 mole of methyl methacrylate, 300 g of tetrahydrofuran (THF), and 0.1 g-3 g of AIBN. The reaction mixture was heated at 60-75° C. for 5-20 hours. The product was precipitated in ethyl ether or n-hexane, filtered and dried to provide poly [2-(toluene-4-sulfonyloxy)ethyl acrylate/3-hydroxypropyl acrylate/-methyl methacrylate] represented by the following chemical formula 17, at a yield of 65-70%.
