Magnesium silicate modified with silanes as filler of polypropylene. Preparation and characterization of composites
MgO center dot SiO2 was pptd. and surface-modified with alkoxysilanes, studied for particle size distribution, N-2 adsorption and dispersive properties and then used as filler of polypropylene-matrix composites. The modified MgO center dot SiO2 particles improved slightly the tensile strength of polypropylene but significantly raised its Young modulus.
