Process for the preparation of polyamines, polyamines and their use in the preparation of polyurethanes |
| abstract |
Polyamines containing primary amino groups are prepared in a single stage process by hydrolyzing an isocyanate in the presence of a catalyst incorporable through an NCO reactive group and a water-miscible aprotic-dipolar solvent. This hydrolysis is carried out at from 20 DEG to 210 DEG C. with the reactants being in substantially homogeneous phase. The isocyanate starting material has an NCO content of from 0.5 to 40% by weight. The catalyst is used in a quantity of at least 0.0001% by weight, based on 100% by weight of isocyanate compound. The water-miscible solvent is used in a quantity of at least 10% by weight, based on 100% by weight of isocyanate compound. The polyamines thus produced are particularly useful in the production of polyurethanes. |
