摘要：
A method for stabilizing a mixture comprising polydiorganosiloxane and an alkali metal. The method comprises contacting a silyl phosphonate described by formula R.sup.1.sub.a (OH).sub.b (OSiR.sup.2.sub.3).sub.3-a-b P.dbd.O, where each R.sup.1 and R.sup.2 is an independently selected hydrocarbyl radical comprising less than about twelve carbon atoms, a=1 or 2, b=0 or 1, and a+b=1 or 2, with a polydiorganosiloxane and an alkali metal.
