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.
Claims11
A process for the production of a molded polymer body with inclusions of fine solid particles composed of a metal, metal compound or a mixture of the same, said polymer being gas-permeable, wettable and at least surface impregnable with a liquid solvent, which process comprises the steps of:
- impregnating said molded body through at least one surface thereof with a liquid solution containing a reactive metal compound;
- and
- introducing a gaseous precipitating agent by direct gassing through the at least one impregnated surface of said molded body for reaction with said reactive metal compound to precipitate fine metal-containing particles within the molded body.
