ABSTRACTSolid sol of silver in poly(methyl methacrylate), Ag/PMMA, was prepared by bulk polymerization of methyl methacrylate solution of silver (I) triflluoroacetate (AgTfa) and followed by postheating. The formation of the metallic Ag nanocluster was characterized by visible spectroscopy, and effects of the concentrations of AIBN and AgTfa and the heat-treatment duration on the formation of Ag cluster were investigated. Furthermore, based on the kinetic study of MMA in the presence of AgTfa, possible mechanism for the reduction and agglomeration of silver is proposed.

Oligomeric Silsesquioxane

A series of poly(methyl methacrylate) (PMMA) composites containing polyhedral oligomeric silsesquioxane (POSS) were produced by bulk polymerization. The morphology, thermal and mechanical properties of the composites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analyses (TGA) and dynamic mechanical analyses (DMA). Results show that the octa(3-chloropropyl)-POSS (ocp-POSS) and trisilanolphenyl-POSS (triol-POSS) have high compatibility with PMMA and can be uniformly dispersed into PMMA matrix. The separate incorporation of these two types of POSS contributes to the improvement of thermal stability of PMMA composites. When the content of POSS was 7.5 wt%, the thermal decomposition temperatures (5% mass loss) of PMMA composites with ocp-POSS and triol-POSS were increased by about 104 °C and 130 °C, respectively. The increase of triol-POSS content in the PMMA matrix gave slight enhanced storage modulus before glass transition.
