Curable polytitanosiloxane compositions and method for preparing cured polytitanosiloxanes using said compositions

摘要

This invention provides curable compositions comprising a polytitanosiloxane containing at least two alkenyl radicals per molecule and a crosslinking agent that is either 1) the combination of an organohydrogensiloxane containing at least two silicon-bonded hydrogen atoms per molecule and a platinum-containing catalyst or 2) an organic peroxide. This invention also provides a method for curing a polytitanosiloxane by reacting it with the crosslinking agent of the present compositions.
