Abstract

PURPOSE: To obtain a high-polymer raw rubberlike organopolysiloxane readily, by reacting a mixture of specific dimethyldiamidosilanes with a diorganopolysiloxane having hydroxyl groups at both ends of the molecular chain.
CONSTITUTION: A diorganopolysiloxane having a relatively low polymerization degree and both ends of the molecular chain terminated with hydroxyl groups is reacted with a mixture of a dimethyl-di(N-methylacetamido)silane expressed by formula I with dimethyl-di(N-ethylacetamido)silane expressed by formula II. The mixing weight ratio between the compound of formula I and the compound of formula II is preferably 0.3W3.0.
