Abstract
1402379 Polyurethanes ATLANTIC RICHFIELD CO 31 July 1973 [30 Aug 1972] 36369/73 Heading C3R [Also in Division C2] Polyurethanes are prepared by reacting an organic compound containing at least two hydroxyl groups with carbon monoxide and a nitrogenous organic compound which has at least two non-cyclic groups in which a nitrogen atom is directly attached to a single carbon atom and is also attached through a double bond to an oxygen or nitrogen atom at an elevated temperature and pressure in the presence of a catalyst which is at least one of selenium, sulphur, a selenium compound, a sulphur compound or a mixture thereof a base and/or water.
