✦ Synopsis

Poly(methyl methacrylate-maleic anhydride) [P(MMA-MAn)] with active groups, anhydrides, was synthesized by radical copolymerization. Using P(MMA-MAn) as a basic polymer, the P(MMA-MAn)/SiO 2 hybrid materials were obtained by a sol-gel process in different ways. The structures of the materials were characterized by IR spectra, and their properties were studied by thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), and dynamic analysis (DA). The results show that the hybrids prepared in different ways have different properties, and the contents of SiO 2 also have influence on the properties of the hybrids.
