Abstract: Grafting polymer chains onto filler particles is an established methodology for creating superior polymer composite materials. Stereocomplexation is a non-bonded interaction between polymers that leads to a crystalline form having a higher melting temperature than the non-stereocomplexed form; stereocomplexed polymers often have superior properties compared to their non-stereocomplexed constituents. The present application discloses combining grafted filler particles with matrix materials in which the grafted polymer layer forms a stereocomplex with the polymer matrix. The resulting composite materials have properties which exceed both filled polymer systems and stereocomplexed polymers.

Abstract: The invention provides methods of producing composite polymers by combining fillers with polymers in the presence of preformed high molecular weight polymer. Monomer polymerization can be initiated through the addition of initiators or by reactive chemical groups on the surface of the fibers. The composite materials formed possess superior mechanical properties compared to similar polymer composites made by either purely mechanical mixing or solely polymerization of monomers in the presence of the fillers.
