Method for the preparation of diorganopolysiloxanes |
摘要 |
A method for the high-purity synthesis of a diorganopolysiloxane having a functional group at only one molecular chain terminal, that is characterized by the preliminary silylation with a silylating agent of the silanol group-containing impurity present in the cyclic trisiloxane, and that is characterized by preliminarily converting the silanol group-containing impurity in the cyclic trisiloxane into a lithiated material by lithiation with an organolithium compound and then silylating this lithiated material using a silylating agent that contains silicon-bonded halogen.
