The platinum-styrene complex used in the following examples is prepared by adding 6 parts of sodium bicarbonate to a mixture containing 3 parts of chloroplatinic acid (H2PtCl6.6H2O), 6 parts of styrene and 50 parts of ethanol. The mixture is heated to reflux temperature (about 55° C.), and then refluxed for about 35 minutes with agitation, and then cooled to room temperature. The resultant mixture is filtered and the crystals thus obtained washed with about 30 parts of acetone. After adding about 30 parts of xylene to the filtrate, orange crystals are formed. These crystals are filtered, recovered and dried. The crystals are dissolved in sufficient isopropanol to form a solution containing 0.75 percent by weight of elemental platinum.
