    摘要: A process for producing a linear organotetrasiloxane comprises the step of hydrolyzing a dihalotetrasiloxane in the presence of an organic compound having at least one epoxy radical. The process prevents effectively the by-production of high molecular weight or cyclic condensates, and yields a linear organotetrasiloxane having a high OH number and high activity.
