<p><P>PROBLEM TO BE SOLVED: To provide, in a method for producing a condensate of a silicon compound soluble in a solvent (hereinafter referred to as a reactive polysiloxane), a production method using a safe acid, other than nitric acid, hardly causing gelling when used for neutralization in a neutralization process after hydrolytic condensation by an alkali catalyst and obtaining the stable reactive polysiloxane. <P>SOLUTION: The production method uses an organic acid in a neutralization process in a method in which neutralization is performed with an acid after performing co-hydrolytic condensation of at least two silicon compounds in alkaline conditions. More preferably, in the method for producing a reactive polysiloxane, a carboxylic acid having pKa of 5 or less is used, and liquid properties of the neutralization liquid after the neutralization has pH of 2 or more and less than 7. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
