Abstract
The present invention relates to multifunctionalized alkoxy, the alkoxy functionality Y being introduced onto a suitable polyhydroorganosiloxane by a dehydrogenation/condensation reaction from the alcohol from which Y derives and then the functionality W by a hydrosilylation reaction from the olefinic compound form which W derives. The multifunctionalized alkoxy polyorganosiloxanes can be used as antiadhesion modulators in silicone compositions and as silica covering agents in silicone compositions containing fillers.
