Abstract: COMPPUNDS CONTAINING THE 2,4,6 - TRIKETO-1,3,5-OXIDAAZINE RING WHICH MAY BE PREPARED BY REACTING AN ORGANIC DIISOCYANATE WITH CARBON DIOXIDE IN THE PRESENCE OF CERTAIN CATSLYSTS INCLUDING PHOSPHINE OR ARSINE CATALYSTS ARE DISCLOSED AS WELL AS POROUS AND NON-POROUS POLMERS BASED ON THE COMPOUNDS CONTAINING THE 2,4,6-TRIKETO-1,3,5-OXADIAZINE RING. THE COMPOUNDS ARE PREPARED BY SATURATING AN ORGANIC POLYISOCYANATE WHERE THE ISOCYANATE GROUPS HAVE APPROXIMATELY EQUAL REACTIVITY WITH CARBON DIOXIDE AND THE CATALYZING THE REACTION OF THE ISOCYANATE WITH THE CARBON DIOXIDE TO YEILD THE 2,4,6-TRIKETO-1,3,5-OXADIAZINE DERIVATIVE.
