Abstract: Metal complexes are obtained by reacting furfurylamine with a metal carbonyl selected from the group consisting of tungsten carbonyl, molybdenum carbonyl and chromium carbonyl. Multi-cycle reimpregnation polymers are obtained by reacting one of these metal complexes with furfuryl alcohol. A carbon/carbon composite is formed by impregnating a carbon/carbon composite containing voids with said polymer and curing and carbonizing said polymer.

Abstract: Improved polyfuran foams are prepared by polymerizing or copolymerizing furfuryl alcohol, alone or in combination with prepolymers or precopolymers of furfuryl alcohol, as liquid feed material in the presence of a liquid acidic compound, the liquid feed material containing at least 20% of free furfuryl alcohol and wherein at least 50% of the hydroxyl groups in the mixture are present as free furfuryl alcohol. The liquid acidic compound or mixture of acidic compounds having a pKa value in water of from 1 to 4 or having a pka value in water of less than 1 and being uniformly distributed in mono alcohols that do not polymerize in the presence of said acidic compound or mixture of acidic compounds. The polyfuran foam having non-flammability characteristics as determined by the muffle furance test.

Abstract: There are disclosed furfuryl alcohol copolymers of a polyester prepolymer of maleic acid or anhydride and a polyhydric alcohol which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the copolymers by reacting the polyester prepolymer with a reaction product of tungsten or molybdenum and pyrrolidine.

Abstract: HALOGENATED SULFONIC ACID ANHYDRIDES (E.G. TRIFULOROMETHYL SULFONIC ACID ANHYDRIDE) ARE USED TO CURE FURFURYL ALCOHOL OR FURAN RESINS, OPTIONALLY CONTAINING A SILANE. THE METHOD FINDS PARTICULAR UTILITY WHERE THE RESINS ARE USED AS FOUNDRY CORE BINDERS, SINCE THE CATALYST CAN BE INTRODUCED IN GASEOUS FORM, AT ROOM TEMPERATURE.
