摘要: The present invention relates to foam compositions which are expanded with hydrohalocarbon blowing agents in the presence of catalysts which are capable of decreasing the amount of decomposition of the hydrohalocarbon blowing agents to haloalkenes during the polymerization. Thus, the present invention provides compositions comprising polyisocyanate, polyol, hydrohalocarbon blowing agent, surfactant, and catalyst for polymerization of the polyisocyanate and polyol wherein the catalyst is capable of decreasing the amount of decomposition of the hydrohalocarbon blowing agents to haloalkenes during polymerization of the polyisocyanate and the polyol.
