Abstract
Description
また、平均分子量が1000以下の比較的重合度の小さいポリエチレングリコールは、電解液に対する溶解性は高いが耐電圧向上の効果が小さい。一方、平均分子量が1000を超えるポリエチレングリコールは、耐電圧向上の効果は高いが、電解液に対する溶解性が低く、多量に添加できないという問題点がある。
また、ポリビニルアルコールも少量の添加で電解液の耐電圧向上を図れるが、電解液に対する溶解性が著しく低いため、長時間の加熱、撹拌を必要とし、作業性にも問題がある。
また、ジメチルアミノエチルアクリレート−プロピレン共重合体は、高温でも分解しにくいので、長期信頼性に優れた電解コンデンサを提供することができる。
また、ジメチルアミノエチルアクリレート−プロピレン共重合体は熱に対しても分解しにくく安定であり、電解コンデンサの高温での特性の安定化を図ることができる。
なお、表1に示す各実施例で用いたジメチルアミノエチルアクリレート−プロピレン共重合体の平均分子量は3000である。また、表1に示す各従来例で用いたポリエチレングリコールおよびポリビニルアルコールの平均分子量は3000である。
また、ポリエチレングリコールやポリビニルアルコールの量を増やした従来例4、6に係る電解液では、溶質が完全に溶解するには至らなかった。
