Described are a process for producing hydrosilylable polyoxyalkylene ethers, comprising the steps of (1) alkoxylation of at least one terminally unsaturated alcohol with alkylene oxides to afford a polyoxyalkylene ether, (2) etherification of the polyoxyalkylene ether from step (1) and (3) neutralization of the product from step (2) under buffered conditions, and hydrosilylable polyoxyalkylene ether mixtures.
