...Polymerization initiators are compounds that can give highly reactive intermediates under appropriate conditions (such as temperature). A typical example is a radical initiator that decomposes to produce radicals (free radicals). Commonly used types of radical initiators include peroxides (such as benzoyl peroxide) and azo compounds (such as azobisisobutyronitrile). For example, when azobisisobutyronitrile is heated, it decomposes to produce radicals as follows: *Some of the terminology explanations that mention "azobisisobutyronitrile" are listed below.

…重合開始剤は適当な条件(温度など)において反応性のきわめて高い中間体を与えることのできる化合物であり,代表的なものは分解してラジカル(フリーラジカル,遊離基)を生じるラジカル開始剤である。よく用いられるラジカル開始剤のタイプに,過酸化物(過酸化ベンゾイルなど)とアゾ化合物(アゾビスイソブチロニトリルなど)がある。たとえばアゾビスイソブチロニトリルの場合,加熱すると次のように分解してラジカルを生成する。… ※「アゾビスイソブチロニトリル」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
