Cyanoformamidyl isocyanates and synthesis thereof |
摘要 |
The monoadduct of a diisocyanate and hydrogen cyanide, a cyanoformamidyl isocyanate, is produced by he reaction of 1 mole of a diisocyanate with 1 mole of hydrogen cyanide. Heterocyclic polymers are produced by the head-to-tail polymerization of cyanoformamidyl isocyanates in an appropriate solvent and in the presence of an effective catalyst.
