Abstract

1339900 Polyurethanes SCHERING AG 29 Dec 1970 [30 Dec 1969] 61422/70 Heading C3R [Also in Division C2] A polyurethane which may be made cellular by including a foaming agent is prepared by reacting a polyisocyanate with a polyhydroxyl mixture comprising (1) an addition product of epichlorhydrin and water and having a molecular weight below 300, the molecular proportion of the epichlorhydrin to water in the addition product being within the range of 2 to 1 to 3 to 1 and (11) a different polyhydroxyl compound.
