  • Patent number: 4312959
    Abstract: Polyurethane foams exhibiting excellent thermal and oxidative stability can be prepared using as the polymerization or gel catalyst a composition containing at least one organotin compound containing phosphorus and at least one organotin compound wherein a halogen atom is bonded to tin or phosphorus. The terminal properties of foams obtained using the present catalyst compositions are superior to those exhibited by foams prepared using gel catalyst compositions wherein tin, phosphorus and a halogen are present but the phosphorus and halogen are not in the same molecule as the tin atom. The halogen containing tin compound and the phosphorus-containing tin compound may be identical or different. The recovery properties of the foam can be improved by the presence of a carboxylic acid in the catalyst composition.

  • Patent number: 4166053
    Abstract: Heat-resistant, polyorganosiloxane elastomers are prepared by reacting a linear, difunctional polyorganosiloxane with a silicon-containing crosslinking agent and a stannous salt of a monoethylenically unsaturated monohydroxy monocarboxylic acid as the curing catalyst. A filler can optionally be included in the formulation. The present catalysts are unique in that they impart a relatively long working life to the uncured composition yet do not catalyze the depolymerization reaction at elevated temperatures as do conventional organotin catalysts such as dibutyltin dilaurate.
