摘要：
A process is disclosed for the preparing silicone polyethers by reacting; (A) a polyether having at least one terminally unsaturated aliphatic hydrocarbon group and an alkali metal content of less than 50 ppm, (B) an organohydrogensiloxane having an acid number of less than 0.005, via a hydrosilylation reaction. The process is particularly useful to prepare silicone polyethers of improved quality via a continuous process.
