Abstract: A molded polymer body with very fine, discrete, solid particles composed of a metal, metal compound or a mixture of the same incorporated within the molded body in a uniform pattern of distribution, substantially free of agglomerations, as obtained by a process of first impregnating the molded body with a bath solution of a metal compound and then gassing the molded body with a gaseous precipitating agent to precipitate the metal-containing particles. The products are especially useful in catalytic membranes, e.g. as used in artificial lungs or artificial kidneys.
