GRAFT POLYMERIZATION OF 2-HYDROXYETHYL METHACRYLATE ON SOY PROTEIN ISOLATE via ATOM TRANSFER RADICAL POLYMERIZATION

通过酰胺化反应在大豆分离蛋白（SPI）表面引入溴原子，合成了大分子引发剂SPI-Br，以CuCI和bpy为催化体系，通过原子转移自由基聚合法（ATRP）合成了大豆分离蛋白-g-聚甲基丙烯酸2-羟乙酯（SPI-g-PHEMA）.用FTIR、^13C-NMR、GPC对大分子引发剂、接枝产物和接枝物降解链进行结构表征．结果表明，得到了表面接枝聚甲基丙烯酸2-羟乙酯长链的大豆分离蛋白接枝聚合物，用紫外分光光度计（UV）、荧光分光光度计、zeta电位和透射电镜（TEM）表征了接枝产物的溶液性质和微观形态．
