ABSTRACT:
The novel organosiloxane compounds of the present invention are characterized by the presence of 1) a silicon atom containing at least two alkoxy or other hydrolyzable groups and the group --OR.sup.1 Si.dbd. wherein R.sup.1 represents a divalent organic group comprising carbon, hydrogen, and, optionally, oxygen, and 2) a silicon bonded hydrogen atom or alkenyl radical. A preferred method for preparing the compounds is by the reaction of 1) a silane containing a silicon-bonded alkenyloxy group and at least two silicon-bonded hydrolyzable groups or a precursor of said hydrolyzable groups and 2) an organohydrogensiloxane. The reaction is conducted in the presence of a hydrosilation catalyst.
