Reduction of free monomer in isocyanate adducts |
| abstract |
REDUCTION OF FREE MONOMER IN ISOCYANATE ADDUCTS ABSTRACT OF THE DISCLOSURE The present invention is directed to a process for reducing the free monomer content of polyisocyanate adduct mixtures wherein the adduct has an average isocyanate functionality of greater than about 1.8 which comprises treating the polyisocyanate adduct mixture in the presence of 2 to about 30 percent by weight of an inert solvent, based on the weight of the polyisocyanate mixture, in an agitated thin-layer evaporator under conditions sufficient to reduce the free monomer content of the polyisocyanate adduct mixture below that level which is obtainable in the absence of a solvent. |
