Stabilisierung von organischen Isocyanaten

摘要

Organic isocyanates are stabilized against decomposition, which results in precipitate formation and discoloration, by the addition of a small amount of an organic isocyanate compound, preferably an oxycarbonyl isocyanate containing at least one -O-CO-NCO group in the molecule. Polyurethane elastomers prepared from isocyanates stabilized in this manner also exhibit a very high resistance to hydrolysis.
