Nitroso perfluoro addition polymers
Abstract
Abstract HIGHLY STABLE COMPLIANT POLYMERS ARE MADE BY REACTING A PERFLUORO ALKYLENE REACTANT WITH DIFLUOROMALEIC ANHYDRIDE AND TRIFLUORONITROSOMETHANE IN THE PRESENCE OF A CATALYST. THESE LINEAR PERFLUORO POLYMERS MAY BE MODIFIED BY INCLUDING IN THE BACKBONE CHAIN A PERFLUORO COMPOUND HAVING A PENDANT OXY STRUCTURE. FURTHER MODIFICATION OF LINEAR RESINS MAY BE OBTAINED BY REACTION WITH AMINE TERMINATED OR DISOCYANATE TERMINATED PERFLUORO CROSS-LINKING COMPOUNDS TO GIVE CURED ELASTOMERS. POLYMERIZATION BY SIMPLE ADDITION REACTION IS MADE OT OCCUR BY THE APPLICATION OF PEROXIDE CATALYST. THESE PERFLUORO POLYMERS MAY BE USED FOR APPLICATIONS AS SEALS, SEALANTS, FILMS, COATINGS, AND FIBERS.
