Abstract
1,193,231. Polyurethanes. FARBENFABRIKEN BAYER A.G. 12 Jan., 1968 [12 Jan., 1967], No. 1787/68. Headings C3C and C3R. Polyurethanes are prepared by reacting polyhydroxyl compounds and polyisocyanates, the polyhydroxyl compounds having added to them 1 to 20% by weight of trioxane. The reaction mixture may contain cross-linking agents, blowing agents, catalysts and other conventional additives. The trioxane particularly serves to lower the viscosity of high viscosity polyhydroxyl compounds so that these become easier to work. Conventional polyethers, polyesters, aliphatic and aromatic polyisocyanates may be used. Water and halogenated hydrocarbons are suitably used as blowing agents and tertiary amines and organotin compounds may be used as catalysts. Emulsifiers, foam stabilizers and flame retardants may also be added.
