DIORGANDPOLYSILOXANE COMPOSITION

This invention relates to compositions which may be stored under anhydrous conditions, but when exposed to atmospheric moisture, crosslink at room temperature to form elastomers. These compositions contain diorganopolysiloxanes having terminal condensable groups, a silicon compound having at least 3...

Beschreibung
Zusammenfassung:	This invention relates to compositions which may be stored under anhydrous conditions, but when exposed to atmospheric moisture, crosslink at room temperature to form elastomers. These compositions contain diorganopolysiloxanes having terminal condensable groups, a silicon compound having at least 3 Si-bonded hydrolyzable groups and an inorganic filler having a surface area of at least 20 m2/g, in which at least a portion of the surface area of the inorganic filler has been modified by having polymerized thereon at least one compound of the general formula HR1C=CHX, where X represents a -CN group or a group of the formula -COOR2, R2 is an alkyl radical having from 1 to 4 carbon atoms and R1 represents hydrogen or a methyl group; or a mixture containing at least one such compound and at least one monomer which has been copolymerized with said compound.
