A modifier for a capacitor electrolytic solution containing (meth) acrylate, an electrolytic solution for an aluminum electrolytic capacitor using the modifier, and an aluminum electrolytic capacitor.

摘要

PROBLEM TO BE SOLVED: To provide a modifier of an electrolytic solution for a capacitor having an excellent effect of improving withstand voltage. SOLUTION: By using a polyoxyalkylene (poly) glyceryl ether (meth) acrylate in which a terminal group of a polyoxyalkylene (poly) glyceryl ether is modified with (meth) acrylate as a modifier, excellent withstand voltage characteristics are obtained. We have found that a capacitor electrolyte can be obtained, and have completed the present invention. [Selection diagram] None
