A polyalkoxysilylalkylenedisilazane of the formula <IMAGE> and a polyalkoxysilylalkylenesilylamine of the formula <IMAGE> 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.
