Process for producing poly (diorganosiloxane) having diorganyloxyorganylsilyl or triorganyloxysilyl end groups, crosslinkable mixtures containing said poly (diorganosiloxane), and methods of use thereof

摘要

In the prepn. of poly(diorganosiloxanes) (I) with terminal di- or tri-organyloxysilyl gps. by reacting alpha , omega -dihydroxy-poly(diorganosiloxanes (II) with alkoxysilane(s) (III), phosphate ester(s) is used as catalyst.
