Claim 1

A METHOD OF PRODUCING A COMPOUND HAVING ONE ISOCYANURATE RING; COMPRISING THE STEP OF REACTING AN ALKALI METAL CYANATE WITH AN ORGANIC HALOGEN COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKYL, ALKENYL AND ARALKYL HALIDE HAVING A MAXIMUM OF 12 CARBON ATOMS AND AT LEAST ONE HYDROGEN ATOM ON THE HALOGEN SUBSTITUTED CARBON ATOM, SAID HALOGEN ATOM HAVING AN ATOMIC WEIGHT OF AT LEAST 35, IN THE PRESENCE OF ABOUT 1 TO 15 MOLES PER MOLE OF THE ALKALI METAL CYANATE INITIALLY PRESENT IN THE REACTION MIXTURE, OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF N-FORMYLMORPHOLINE, N-ACETYLMORPHOLINE, DIMETHYLSULFOXIDE, DIMETHYLSULFONE, TETRAMETHYLENESULFOXIDE AND TETRAMETHYLENESULFONE, FOR A PERIOD OF MORE THAN 1 HOUR AT A TEMPERATURE BETWEEN 100*C. AND 180*C.

Claim 2

A METHOD OF PRODUCING A POLYMER HAVING MORE THAN ONE ISOCYANURATE RING; COMPRISING THE STEP OF REACTING AN ALKALI METAL CYANATE WITH AN ORGANIC HALOGEN COMPOUND HAVING A MAXMIUM OF 12 CARBON ATOMS AND BEING SELECTED FROM THE GROUP CONSISTING OF ALKYLENE DIHALIDE, ARALKYLENE DIHALIDE, BIS (HALOALKYL) ETHER, BIS (HALOALKYL) SULFONE, TRIS (HALOALKYL) CYANURATE AND TRIS (HALOALKYL) ISOCYANUARATE HAVING AT LEAST ONE HYDROGEN ATOM ON EACH HALOGEN SUBSTITUTED CARBON ATOM, EACH HALOGEN ATOM HAVING AN ATOMIC WEIGHT OF AT LEAST 35, IN THE PRESENCE OF 1 TO 15 MOLES, PER MOLE OF ALKALI METAL CYANATE INITIALLY PRESENT IN THE REACTION MIXTURE, OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF N-FORMYLOMORPHOLINE, N-ACETYLMORPHOLINE, DIMETHYLSULFOXIDE, DIMETHYLSULFONE, TETRAMETHYLENESULFOXIDE AND TETRAMETHYLENESULFONE, FOR A PERIOD OF MORE THAN 1 HOUR AT A TEMPERATURE BETWEEN 100* C. AND 180* C.
