Anionic addition polymerization is not confined to vinyl compounds. It equally occurs when 1,2-epoxyethane (commonly known as [[ethylene oxide]]) reacts with a small amount of a [[base (chemistry)|base]], such as sodium [[methoxide]]. It turns, through polymerization , into a [[polyether]] of high molecular weight.
