Abstract
1463003 Thixotropic polyurethane compositions DAI ICHI KOGYO SEIYAKU CO Ltd 29 Jan 1974 04033/74 Heading C3R Thixotropic polyurethane compositions comprise (a) a liquid comprising a polyurethane prepolymer having at least two terminal free isocyanate groups and (b) a block polyether having at least two terminal hydroxyl groups, the secondary alcohol group content being 40 to 85% with respect to the total number of terminal groups, and being the reaction product of a starting material having 2 or 3 terminal active hydrogen groups and ethylene oxide and propylene oxide in a block form, such that per mole of polyether there is used 30 to 409 moles of ethylene oxide and 3 to 172 moles of propylene oxide and the molar ratio between ethylene oxide and propylene oxide is from 1: 0À05 to 1 : 0À5. The compositions may also contain an inorganic material which enhances the thixotropy of the composition, e.g. silica or bentonite. The prepolymer where it exists in the liquid phase may be used as such or, alternatively, if the prepolymer exists normally as a solid it may be used dissolved in an organic solvent. In the preparation of the block polyether it is preferred to first react the starting material with ethylene oxide and then with propylene oxide. Starting materials for the polyether used in the examples are ethylene glycol, propylene glycol, glycerol, and triethanolamine. The compositions cure to form polyurethane elastomers.
