CYANO-ETHER POLYALKYLSILOXANE HYDRIDES ABSTRACT OF THE DISCLOSURE Cyano-ether polyalkylsiloxane hydrides are provided which comprise monofunctional siloxy units and difunctional siloxy units, an average of between about 2 and about 100 silicon-bonded cyano-bearing ether groups for every two moles of monofunctional units, said cyano-bearing ether groups having the formula, -(O)qR'OR"CN, wherein q is zero or one, R' is bivalent alkylene of 3 to 8 carbon atoms and R" is bivalent alkylene of 2 to 4 carbon atoms, and an average of between about 2 and about 30 silicon-bonded nydrogen atoms for every two moles of monofunctional units, said monofunctional units having at least two alkyls bonded to the respective silicon atoms thereof and the difunc- tional units having at least one alkyl bonded to the respective silicon atoms thereof, the remaining group bonded to silicon of the respective monofunctional and difunctional siloxy units being alkyl, said cyano-bearing ether group or hydrogen. The polyalkylsiloxane hydrides of the invention are especially useful as hydrosilation and condensation agents in the formation of corresponding cyanoalkoxyalkyl- and cyanoalkoxyalkoxy-substituted poly- alkylsiloxane-polyoxyalkylene copolymers.
