Notes:
Because of its possible use as a blocked “post-polymerization crosslinking agent” for polymers containing labile hydrogen, the structure of the acetone oxime adduct of 4,4′-methylenebis-(phenylisocyanate) has been determined. 13C and 1H nuclear magnetic resonance (NMR) spectroscopy has identified this product to be N,N′-(2-propyloximino)-4,4′-methylenebis(phenylcarbamate). Chemical shift assignments were based on information obtained by proton decoupled, off-resonance decoupled, and gated decoupled 13C-NMR, proton-NMR, and semiemperical substituent chemical shift (SCS) parameters.
