| abstract |
A Process for the Production of a Polyisocyanate, and Polysocyanate A process for the production of a polyisocyanate composed of (a) phosgenation of a polyamine to form a polyisocyanate by reacting (1) a polyamine, the polyamine on which the polyisocyanate is based. in solution is in an inert solvent with (2) phosgene, optionally in solution in an inert solvent, (b) solvent separation from polyisocyanate, (c) treatment of the separated solvent to be reusable in polyamine solution (1) with an isocyanate trimerization catalyst. |
