Notes:
Useful isocyanate-containing polymers may be made by reacting amide copolymers with a hypochlorite such as sodium hypochlorite. A highly branched carbon structure adjacent to the amide is required, otherwise the isocyanate is lost through reaction with components of the reaction mixture. The polymeric isocyanates react rapidly with monomeric and polyamines and at adequate rates with hydroxyl compounds. These polymers are very useful in paint films and other applications due to their ability to undergo crosslinking and chain extensions by reaction of the isocyanate groups.
