ABSTRACT:
Composites of heat-stable thermoplastic polymers and silica reinforcing fibers having diameters of less than 1000 nm are prepared by polycondensation of silicic acid or polysilicic acid in the melt or solution of the thermoplastic under the influence of a high shear gradient. The silicic acids or polysilicic acids are salted out from aqueous solution in order to transfer then to an organic solvent, which is also a solvent for the thermoplastic.
