ORGANO-METAL CATALYSTS AND PROCESSES FOR THEIR PREPARATION

摘要

Metal catalysts for use in known heterogeneous catalysis processes are prepared by vaporizing a metal in a low pressure environment in the vicinity of an organic liquid polymer, so that the metal contacts and becomes anchored to the polymer. The resulting products have the metal in the form of small clusters, anchored to the polymer, this form of the metal being the catalytically most active form. The organometal polymers are stable at temperatures in the -40.degree.C?+40.degree.C range. Suitable polymers include poly (methyl-phenyl siloxanes) and poly (phenylethers). Suitable metals include titanium, chromium, molybdenum, etcetera.
