Document Type and Number:
WIPO Patent Application WO/2015/174389
Kind Code:
A1
Abstract:
Provided is a method for producing an organopolysiloxane emulsion composition which contains an organopolysiloxane having a trialkyl group at a terminal thereof and having a viscosity of 50,000 mm2/s or more at 25ºC, within a shorter time compared with the conventional methods.
A method for producing an emulsion composition which contains an organopolysiloxane having a viscosity of 50,000 mm2/s or more at 25ºC and capped with a trialkylsilyl group, said method comprising: (I) emulsifying a mixture comprising (A) an organopolysiloxane, (B) a nonionic surfactant, (C) an anionic surfactant, (D-1) an acidic compound and (E-1) water to prepare an emulsion composition; (II) adding (D-2) an acidic compound and (E-2) water to the emulsion composition to perform emulsion polymerization; and (III) adding 0.001 part by mass or more of (F) a compound to the resultant product to perform emulsion polymerization again.
