Title:
POLYORGANOSILOXANE, POLYORGANOSILOXANE COMPOSITION, CURED PRODUCT, POLYORGANOSILOXANE-CONTAINING ELECTROLYTIC SOLUTION FOR ELECTROLYTIC CAPACITOR, AND ELECTROLYTIC CAPACITOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/110613
Kind Code:
A1
Abstract:
Provided are: a polyorganosiloxane having high elasticity, high strength, excellent dimensional stability, and the like; an electrolytic solution which is for an electrolytic capacitor and contains the polyorganosiloxane; and an electrolytic capacitor using the electrolytic solution. The polyorganosiloxane contains 10 mol% or more of an M unit (R1 R2 R3 SiO1/2) with respect to total silicon and 80 mol% or less of a T unit (R6 SiO3/2) with respect to total silicon, and has a silicon-bonded alkoxy group and silicon-bonded reactive functional groups other than the alkoxy group, the polyorganosiloxane being characterized in that the content of the silicon-bonded alkoxy group with respect to the total weight of the polyorganosiloxane is 0.07-4 wt%, the number of the silicon-bonded reactive functional groups is 3-12 per 1000 of the molecular weight of the polyorganosiloxane, and the weight loss of the polyorganosiloxane when heated at 110°C for 2 hours under a reduced pressure of 0.15 torr is 5 wt% or less, wherein R1, R2, R3, and R6 are each independently a hydrogen atom, or an organic functional group other than an alkoxy group or hydroxyl group, and may be identical to or different from each other.
