Because the reaction is initiated by the attachment of an electrophile, the process is called an electrophilic addition reaction .

因为反应电试的附加而开始的，所以这个过程叫电加成反应。

In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.
