His expertise and creativity have led to advancements that benefit various applications in the chemical industry.

Latest Patents

One of his latest patents involves biuret polyisocyanates, which correspond to the formula ##STR1## wherein R is --CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 -- and X is hydrogen or --C(O)--NX--R--NCO. These compounds contain no more than six isocyanato groups per molecule and are prepared by reacting bis(2-isocyanatoethyl)ether with water in a mole ratio of at least 3 moles of diisocyanate per mole of water. The biuret polyisocyanates are particularly useful in the preparation of polyurethanes. Another patent focuses on N,N-di(carbonyl chlorides) of N,N'-alkylene ureas, which are compounds of the formula ##STR1## wherein --R-- is di-, tri- or tetramethylene that may bear from 1 to 8 C.sub.1 -C.sub.3 alkyl substituents. This process involves contacting a reactant of the formula ##STR2## with COCl.sub.2 at reaction temperature. For instance, 2-imidazolidone is contacted with phosgene to form N,N'-bis(carbonyl chloride)-2-imidazolidone. These compounds can be condensed with polyols, polythiols, or polyamines to form useful resins or pyrolyzed to yield alkylene diisocyanates.
