Aniline resin - aniline resin

Japanese: アニリン樹脂 - アニリンじゅし(英語表記)aniline resin
Aniline resin - aniline resin
A resin made by condensing aniline C6H5NH2 and formaldehyde HCHO in the presence of hydrochloric acid. As this reaction continues, a three-dimensional network structure forms and hardens, becoming a thermosetting resin. It has excellent electrical properties and was once used as an electrical insulator, but today it has been replaced by epoxy resins and phenolic resins. Recently, low molecular weight resins have been made and are only used as epoxy resin hardeners and phenolic resin modifiers. [Morikawa Masanobu]

Japanese:
アニリンC6H5NH2とホルムアルデヒドHCHOを塩酸の存在下で縮合させてつくられる樹脂。この反応を続けていくと三次元の網目構造が形成されて硬化し,熱硬化性樹脂となる。電気特性にすぐれ,かつては電気絶縁体製品として使用されたが,現在では,エポキシ樹脂やフェノール樹脂にとって代わられている。最近では低分子量の樹脂をつくり,エポキシ樹脂の硬化剤,フェノール樹脂の改質剤などに用いられているにすぎない。【森川 正信】
