Abstract
AbstractBecause 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.
