Procedure

The process described in Example I was repeated substituting 59.95 parts of m-aminophenol for the p-aminothiophenol and 78.9 parts of bis-(chloropropyl) tetramethyldisiloxane for the bis-(chlorobutyl)tetramethyldisiloxane. The end product was recovered by distillation within the temperature range of from 245° C. to 260° C. under a pressure of from 0.5 mm to 2.0 mm of mercury. This product was identified as bis-(aminophenoxypropyl)tetramethyldisiloxane, a pale yellow liquid which did not solidify upon standing at 0° C. for three days. Its pority, as determined by titration with perchloric acid, exceeded 99%.
