Abstract
Curable polyorganosiloxanes prepared using a base-catalyzed equilibration reaction involving at least one organosiloxane are treated with a composition that includes a triorganohalosilane to neutralize the catalyst. The silane can be used alone or in combination with other Lewis acids. Curable compositions containing polyorganosiloxanes prepared using the present method exhibit improved thermal stability relative to compositions containing polyorganosiloxanes prepared using prior art neutralizing agents.
