摘要：

Activators generated by electron transfer for atom transfer radical polymerization (AGET ATRP) of methyl methacrylate (MMA) on silica nanoparticles were conducted to create controllable shell on silica surfaces. SiO2-Br, the macroinitiator, was prepared by the reaction of amido groups previously indroduced on silica with 2-bromoisobutyryl bromide, followed by the ATRP of MMA using CuBr as the catalyst and ascorbic acid (VC) as the reducing agent in the presence of a limited amount of air. The resulting particles were examined by SEM and TEM. The results indicated that the particles were composed of a silica core and a densely grafted outer poly(methyl methacrylate) (PMMA) layer.
