MANUFACTURING METHOD OF CONDENSATION REACTION PRODUCT, ROOM TEMPERATURE CURABLE ORGANOPOLYSILOXANE COMPOSITION CONTAINING THE CONDENSATION REACTION PRODUCT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a condensation reaction product of which manufacturing is simple and tact time is short, a room temperature curable organopolysiloxane composition containing the product as a main agent, a manufacturing method therefor or the like.;SOLUTION: There is provided a manufacturing method of a condensation reaction product obtained from (A) a polysiloxane resin with a three dimensional network structure having a molar ratio of R₃SiO_1/2 to SiO_4/2 of 0.5 to 1.5, a silanol group of a specific amount and a molecular weight of 4,000 to 10,000, (B) a silane compound having two or more hydrolyzable groups and/or a partial hydrolyzed condensate thereof, (C) linear diorganopolysiloxane of which both terminals of a molecule chain is encapsulated with SiOH and (D) amino group-containing silane and/or a partial hydrolyzed condensate thereof, including (i) a process for condensation reaction between (A) and (B) using (D) as a catalyst to introduce the hydrolyzable group of (B) to the silanol group of (A) and (ii) a process for further condensation reaction of the condensation reaction product of the (A) and (B) with (C) in a specific mass ratio.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
