e/Ring-opening polymerization

Information
has gloss	eng: In polymer chemistry, ring-opening polymerization is a form of addition polymerization, in which the terminal end of a polymer acts as a reactive center, where further cyclic monomers join to form a larger polymer chain through ionic propagation. The treatment of some cyclic compounds with catalysts brings about cleavage of the ring followed by polymerization to yield high-molecular-weight polymers. Exemplary polymers produced by this method include Nylon 6 and polyethylene oxide.

Meaning
Japanese
has gloss	jpn: 開環重合（かいかんじゅうごう）は環状化合物の環構造を解き、環の解かれた化合物の端同士が結合することで重合体とする反応である。合成繊維の6-ナイロンやナイロン-12はラクタムの開環重合により製造される。
