ABSTRACT:
A composite material having a high molecular weight polymer material as the matrix material and extremely fine particles of diameters of the order of tens to hundreds of angstroms dispersed in the matrix material is obtained by rapidly adiabatically cooling vapor of a metallic material through a nozzle, and squirting a jet of said fine particles into a molten mass of the high molecular weight polymer material. Optionally, inert gas may be squirted through the nozzle along with the vapor of the metallic material. Further, optionally a gas which forms a compound with the metallic material may be squirted through the nozzle with vapor of the metallic material, so that the particles become particles of a compound of the metallic material and the gas.
