ABSTRACT:
A polyalkoxysilylalkylenedisilazane of the formula ##STR1## and a polyalkoxysilylalkylenesilylamine of the formula ##STR2## where x is 0 or 1; R is a saturated alkyl or aryl radical or mixture of radicals; R' is alkyl, aryl, or Cellosolve (R) alkylethanol radical, or mixture of radicals; R" is hydrogen, alkyl, aryl, or aryalkyl radial or mixture of radicals; and A is a divalent hydrocarbon radical having 2 to 20 carbon atoms; and a method for their manufacture by the platinum catalyzed addition of an alkenyl- functional disilazane or silylamine with an alkoxy-functional silicon hydride is disclosed. The silylamine can also be produced by the platinum catalyzed addition of a SiH functional silazane or silylamine and an alkenyltrialkoxysilane. The polyalkoxysilylalkylenedisilanzane and the polyalkoxysilylalklylenesilylamine can be reacted with a silanol containing polyorganosiloxane such as a hydroxyl endblocked polydiorganosiloxane in the presence of an acidic catalyst to give a polyalkoxysilyl terminated polydiorganosiloxane in which the terminal groups are bonded to the polymer through an alkylene linkage.
