Preparation of alkoxysilethylene endblocked polydiorganosiloxane

Preparation of alkoxysilethylene endblocked polydiorganosiloxane

A method of producing alkoxysilethylene endblocked polydiorganosiloxane consists essentially of first reacting hydroxyl endblocked polydiorganosiloxane with excess SiH compound having from 2 to 4 SiH groups in the presence of a platinum catalyst, then reacting that product with vinyltrialkoxysilane...
