Abstract

Polyurethanes are prepared by reacting an organic polyisocyanate with a polyether obtained by reacting a cyclic polyhydroxy compound containing 4 or more hydroxy groups with a 1,2-alkylene oxide, in a reactive medium which consists of one or more acylic compounds containing 4 or more hydroxy groups and which has a melting point of at most 120 DEG C. The polyethers may be prepared from sucrose, glucose, a -methyl glucoside, anhydroenneaheptitol, or a water-soluble partially hydrolysed starch. Specified media are sorbitol and a mixture thereof with mannitol, e.g. in the proportions 3: 1. The 1,2-alkylene oxide may be ethylene oxide, propylene oxide or a butylene oxide. The average number of alkylene oxide units per hydroxy group varies from 1.67 to 1.75 in the examples. In Example (2) a rigid foamed polyurethane is prepared using the polyether, triethylene diamine, triethylamine, a siloxane-polyoxyalkylene block copolymer surfactant and foam-stabilizer, and trichlorofluoromethane with toluene diisocyanate.ALSO:Polyethers are prepared by reacting a cyclic polyhydroxy compound containing four or more hydroxy groups with a 1,2-alkylene oxide, in a reactive medium which consists of one or more acyclic polyhydroxy compounds containing four or more hydroxy groups and which has a melting point of at most 120 DEG C. The polyethers may be prepared from sucrose, glucose, a -methyl glucoside, anhydroenneaheptitol, or a water-soluble partially hydrolysed starch.
