The homopolymer brushes of polyacrylamide(PAAM) on spherical silicon gel were synthesized by atom transfer radical polymerization(ATRP). The silicon gel initiator was prepared by self-assemble. Utilizing these modified silicon gel as the substrate, a kind of novel inorganic-organic hybrid material with the polymer metal complex was synthesized. The result of ESR indicates that the inorganic/organic hybrid material with the polymer metal complex based on silicon gel possesses well paramagnetis.
A novel graft macromolecular coupling agent with well-defined structure was synthesized by atom transfer radical polymerization(ATRP). Since the silicon of graft polymers possesses a strong affinity to hydroxyl mineral, it gives fillers some new properties such as the increase of the interaction of fillers with matrix. The properties, structure of macromolecular coupling agent and its composite were studied by dynamic mechanical spectra, IR, UV, NMR, GPC and SEM.
