摘　　要：通过溶胶凝胶法在常温下制备出纯纳米TiO2,通过浸渍、沉淀、抽滤等步骤得到改性纳米TiO2.同时用改性后的纳米TiO2引发APEG、MA、马来酸单甲酯三元共聚,并优化反应的条件,结果表明:当引发剂用量为反应物总质量的6%,光照时间为4h,H2O2的量为1.5mL并控制反应温度为100℃,反应时间为10h时,其转化率最高可以达到74.29%.TiO2 nanoparticles were synthesized by sol-gel method under the normal temperature.The modified TiO 2 were prepared by impregnation,precipitation,filtration and other steps.It triggered APEG,MA,monomethyl maleate to copolymerize,and to optimize the reaction conditions.The results showed that as the amount of initiator was 6%,the irradiation time was 4h,the amount of H2O2 was 1.5mL and the reaction temperature was 100℃for 10h,the conversion rate can reach 74.29%.
