Abstract
Cellular polyurethane exhibiting excellent thermal and oxidative stability can be prepared using specified methyl-, allyl-, phenyl- or benzyltin compounds as the polymerization catalyst. These catalysts are hydrolytically stable over extended periods of time, and can therefore be incorporated into precursors or masterbatches for polyurethanes that contain water as the foaming agent.
