ABSTRACT:
Compounds of metals from the platinum group of the periodic table compounds are encapsulated within a thermoplastic organic polymer using known prior art techniques. The presence of trace amounts of the encapsulated compound on the surface of the microcapsules is avoided by preparing the microcapsules by in-situ polymerization or precipitation of the encapsulant, followed by washing of the microcapsules with a solvent for the encapsulated compound that will not dissolve or swell the encapsulating polymer.
