| titleOfInvention |
Liquid polyisocyanate mixtures, a process for their preparation, and their use in the preparation of polyurethane foams |
| abstract |
This invention relates to novel urethane-modified polyisocyanate mixtures of the diphenylmethane series prepared by a process comprising reacting polyisocyanates or polyisocyanate mixtures of the diphenylmethane series with certain monohydric and/or polyhydric alcohols and, optionally, subsequently mixing the initially modified products with polyisocyanates or polyisocyanate mixtures of the diphenylmethane series that have not been modified with urethane groups. This invention further relates to the use of the polyisocyanate mixtures in the preparation of polyurethane foams. |
