摘要

Poly(methyl methacrylate-maleic anhydride)[P(MMA-MAn)]with active proups,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.
