    摘要： TDI residue-based urethane-filled isocyanate compositions are produced by reacting a TDI residue satisfying specified criteria with a monofunctional alcohol in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 0.9:1 to about 1:0.9. This reaction product is then dissolved in a diisocyanate or polyisocyanate before, during or after reaction of that product with an epoxide having an epoxide equivalent weight of from about 44 to about 400 at a temperature of up to 120.degree. C. These TDI residue-based urethane-filled isocyanate compositions are particularly useful in the production of polyurethanes.

    摘要： The present invention relates to a liquid, storage-stable isocyanate having a viscosity of less than 100,000 mPa.s at 25.degree. C. and an isocyanate content of from about 10 to 29% by weight, and is prepared by reacting a solid or semi-solid diphenylmethane diisocyanate with a blocking agent. More generally, the liquid isocyanate is prepared by reacting the solid or semi-solid diphenylmethane diisocyanate with the blocking agent in quantities such that from 7 to 55% of the isocyanate groups are blocked. Preferred blocking agents are the ketoximes, and mixtures thereof.
