Abstract

PURPOSE:To obtain the titled substance without crystallinity, corrosiveness for metal and swelling of plastics, by reacting a specific diorganopolysiloxane with specific organosilicon compound using a specific silane, etc., as a catalyst. CONSTITUTION:(A) A diorganopolysiloxane having both terminals of molecular chain sealed with silanol groups is reacted with (B) an organosilicon compound expressed by formula I (R<1> is methyl, vinyl, trifluoropropyl or phenyl; R<2> is methyl, vinyl, trimethylsiloxy, vinyldimethyksiloxy, etc.; R<3> is methyl or ethyl) (e.g. a compound expressed by formula II) in the presence of (C) a silane or siloxane having at least one group expressed by the formula (R2<4>N)2C=N- (R<4> is H or monofunctional hydrocarbon) in one molecule (preferably a compound expressed by formula III, etc.) as a catalyst to afford the aimed compound.
