Notes:
Bis(4,4′-phenylisocyanato) dimethylsilane (SiDI) and 2,2-bis (4,4′-phenylisocyanato)propane (PrDI) were synthesized, polymerized to polyurethanes, and their chemical, thermal and physical properties studied. Nuclear magnetic resonance spectra confirm deshielding by silicon of both the phenyl ring and the urethane linkage. The glass transition temperatures, solubility parameters, and mechanical properties were independent of the diisocyanates. The silicon containing polyurethanes are more thermally stable than their carbon counterparts. © 1993 John Wiley & Sons, Inc.
