| titleOfInvention | A process for the production of polyhydrazodicarbonic acid amides or polyureas |
| abstract | Polyureas or polyhydrazides containing alcoholic -OH groups are prepared by reacting an aromatic diisocyanate at -20 DEG to +30 DEG C. in an organic solvent with an equivalent amount (i.e. one NCO group per -NH group) of a carbonic or sulphurous acid salt of a diamine or hydrazine containing alcoholic -OH groups, and at least one active hydrogen atom on each of the N atoms. The salt may be prepared in situ by the reaction of SO2 or CO2 with a diamine or hydrazine containing -OH groups. The solvent may be a polar solvent, e.g. dimethyl formamide, dimethylacetamide, N-methyl pyrrolidone, dimethyl sulphoxide or tetramethyl urea. In the examples various diisocyanates were reacted with the salts of (1) N-(b -hydroxypropyl) hexanediamine, (2) N-(b -hydroxybutyl) hexane diamine, (3) N-(b -hydroxy-b -phenylethyl) hexanediamine, (4) N-(b -hydroxy-g -phenoxypropyl) -hexanediamine, (5) N-(b -hydroxy-g -allyloxypropyl) hexane diamine, (6) N-(b -hydroxypropyl) xylylene-1,3-diamine, (7) N1 - [g - (b - hydroxy - b - phenylethyl)] - N - methyl bis propylene diamine, (8) 1,3-diaminopropan-2-ol and (9) b -hydroxyethylhydrazine. |
