Bridged isocyanurates

Abstract

Abstract BRIDGED ISOCYANURATE (BIC) DERIVATIVES AND RESINS, INCLUDING POLYESTERS, POLYESTER-AMIDES, POLYESTER-IMIDES, POLYESTER-AMIDE-IMIDES, ETC., PREPARED FROM BRIDGED ISOCYANURATE DERIVATIVES, I.E. COMPOUNDS OR POLYMERS CONTAINING AT LEAST TWO BRIDGED ISOCYANURATE UNITS PREFERABLY DERIVED FROM HYDROXYALKYL, SUCH AS HYDROXYETHYL, ISOCYANURATES AND MOST PREFERABLY FROM TRIS (2-HYDROXYETHYL) ISOCYANURATE OR ITS EQUIVALENT. EXAMPLES OF THE BRIDGING UNIT COMPRISE (1) EITHER GROUPS, (2) ACETAL GROUPS, (3) CARBONATE GROUPS (4) HYDROCARBON GROUPS, (5) URETHANE GROUPS AND (6) COMBINATIONS THEREOF, ETC. RESINS DERIVED FROM BIC DERIVATIVES MAY ALSO BE BLENDED AND/OR COPOLYMERIZED WITH HYDANTOIN POLYMERS TO YIELD HYDANTOIN BIC POLYMERS. THE HYDANTOIN POLYMERS EMPLOYED MAY BE PREPARED BY REACTING POLYGLYCINES AND POLYISOCYANATES, AND MOST PREFERABLY DIGLYCINES AND DIISOCYANATES. THESE RESINS MAY BE CURED BY USING CONVENTIONAL CURING AGENTS, CURING RESINS SUCH AS MELAMINE-ALDEHYDE, PHENOL-ALDEHYDE, ETC. RESINS. THESE RESINS MAY BE EMPLOYED IN ELECTRICAL INSULATION, PARTICULARLY AS WIER ENAMELS, AND FOR OTHER USES.
