Abstract
Diorganotin compounds wherein at least one of the remaining valences on the tin atom is satisfied by a sulfur atom or a thiocyanate group are unique among diorganotin compounds in that they retain their catalytic activity over extended periods of time in the presence of the precursors or masterbatches conventionally employed to prepare rigid, cellular polyurethanes.
