polymer-silicate filler

The influence of the nature of modified fillers (Ni- and Cu- containing polymer-silicate materials) on the kinetics of emulsion polymerization of methyl methacrylate in the presence of polyvinylpyrrolidone graft copolymers was investigated. The effect of modified metal-containing silicate fillers on the technological properties of the developed materials was determined. In particular, the introduction of fillers contributes to a significant reduction of technological shrinkage and moisture absorption of polymethyl methacrylate materials.

The features of obtaining and modifying Ba- and Zn-containing polymer-silicate fillers have been researched. The influence of polystyrene modifiers (suspension and impact-resistant polystyrene) and finely dispersed Ba- and Zn-containing polymer-silicate fillers on the gelation process, view of flow curves, rheological properties: flow index, flow limit, thermal stability, surface hardness and elasticity of plasticized poly(vinyl chloride) have been discovered.
