| titleOfInvention | PROCEDURE FOR THE PREPARATION OF THE NEW POLIISOCIA-NATOS. |
| abstract | Procedure for the preparation of the new polyisocyanates of the formula **(See formula)** in which A stands for an aliphatic, cycloaliphatic, cycloaliphatic-aliphatic, araliphatic, aromatic or heterocyclic-aliphatic radical (n + 1) -valent; B designates a divalent aliphatic, cycloaliphatic, cycloaliphatic-aliphatic or araliphatic radical; R1, R2, R'1 and R'2 each mean a hydrogen atom or a cycloaliphatic, araliphatic or aromatic aliphatic hydrocarbon radical, or R1 and R2 and respectively R'1 and R'2, together, form a hydrocarbon radical divalent aliphatic or cycloaliphatic; and n represents an integer valued from 1 to 10 at least and from 3 at most; characterized by reacting, with heating, 1 mole of a bis-hydantoin of the formula **(See formula)** with 2 moles of a polyisocyanate of the formula A [-R = C = O] n + 1 (Machine-translation by Google Translate, not legally binding) |
