Abstract
1339931 Polyurethanes JEFFERSON CHEMICAL CO Inc 13 July 1971 [10 Aug 1970] 32746/71 Heading C3R [Also in Division C2] Polyurethanes are prepared by reacting an organic polyol (I) with an organic polyisocyanate (II) in the presence of a catalytic amount of 2 - (N,N - dimethylamino)ethyl 3 - (N,N - dimethylamino)propyl ether (III). I may be a linear polyether polyol, M.W. 2000-7000, a branched (3 to 7 OH groups) polyether polyol of M.W. 300-700 or a polyester polyol M.W. 2000-4000. II may be tolylene diisocyanate used so as to provide 1À0-1À5 isocyanate equivalents per hydroxyl equivalent of I. III may be used at 0À02-0À2% wt. of I+II. Examples relate to foam preparation. Specification 1,090,192 is referred to.
