Abstract

Compositions which are stable when stored under anhydrous conditions, but when exposed to atmospheric moisture cross-link to form elastomers comprising (1) an organopolysiloxane having terminal condensable groups, (2) a silicon compound having at least 3 Si-bonded hydrolyzable groups per molecule and (3) from 30 to 100 percent by weight, based on the weight of the organopolysiloxane (1), of a powder obtained from the homopolymerization or copolymerization of an acrylonitrile in an aqueous medium.
