Abstract: Biuret-containing polyisocyanates are prepared by reacting organic polyisocyanates with secondary amines at temperatures of from about 80* to about 200*C. The polyisocyanates which contain biuret groups are useful as isocyanate precursors in the preparation of polyurethane plastics by the isocyanatepolyaddition process.

Abstract: Novel aromatic diamines having the general formula

WHEREIN N IS AN INTEGER OF FROM 2 TO 8, X is sulfur or oxygen, and R is an n-valent hydrocarbon radical which may be interrupted by O or S atoms and which is obtained by removing OH or SH groups from a polyol or polythiol having a molecular weight of less than 600, are prepared by reacting a compound having the formula (HX)nR where X, n and R are as defined above with about nequivalents of an isatoic acid anhydride in the presence of a strong base. The aromatic diamines of the invention are particularly useful as the active hydrogen containing component for reaction with polyisocyanates in the preparation of synthetic resins by the isocyanate-polyaddition process.
