Patent number: 4223111Abstract: A process is described for the preparation of a polymer having a recurring unit of the formula: ##STR1## where R is hydrogen or methyl, C.sub.n H.sub.2n is lower-alkylene, R.sub.1 and R.sub.2 are aryl and x is 0 or 1. A polymer having a recurring unit of the formula: ##STR2## where X is chloro, bromo, iodo, chloroalkyl, bromoalkyl or iodoalkyl, is reacted with a triarylarsine in the presence of lithium or sodium-potassium alloy. The resulting polymer is an intermediate in the preparation, by oxidation, of the corresponding As-oxide. The latter is useful as a catalyst for the conversion of isocyanates to the corresponding carbodiimides.Type: GrantFiled: August 27, 1979Date of Patent: September 16, 1980Assignee: The Upjohn CompanyInventors: Curtis P.

Patent number: 4197220Abstract: Amine containing polymeric microspheres such as polyvinyl pyridine are complexed with metal salts or acids containing metals such as gold, platinum or iron. After reduction with sodium borohydride, the salt is reduced to finely divided free metal or metal oxides, useful as catalysts. Microspheres containing covalent bonding sites can be used for labeling or separating proteins.Type: GrantFiled: May 26, 1978Date of Patent: April 8, 1980Assignee: California Institute of TechnologyInventors: Alan Rembaum, Willi Volksen

Patent number: 4185043Abstract: There are disclosed thermoplastic and thermosetting polymers which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the polymer by reacting a monomer or polymer containing at least one free carboxyl group with a reaction product of tungsten or molybdenum and pyrrolidine.Type: GrantFiled: April 5, 1978Date of Patent: January 22, 1980Assignee: HitcoInventor: Robert C.
