Alpha-alkoxy-omega-siloxanols, R'O(R2SiO)xH, are produced by contacting cyclic siloxanes with alcohols under mild conditions. For example, hexamethylcyclotrisiloxane heated at reflux in methanol for four hours gives 5-methyoxyhexamethyltrisiloxan-1-ol in high yield. The reaction proceeds more rapidly in the presence of weak acids or bases. The products are useful as coupling agents, as antistructure agents and filler-treating agents for silicone elastomers.
