ABSTRACT:
Flexible cellular polyurethane exhibiting excellent thermal and oxidative stability can be prepared using specified complexes of organotin halides or pseudo halides with amines, phosphines or phosphine oxides as latent polymerization catalysts. These catalysts also eliminate the shrinkage that often characterizes cellular polyurethanes prepared using organotin compounds as the polymerization catalyst.
