===Initiation by strong anions===
 
[[Nucleophilic]] initiators include covalent or ionic metal [[amide]]s, [[alkoxide]]s, [[hydroxide]]s, [[cyanide]]s, [[phosphine]]s, [[amine]]s and organometallic compounds (alkyllithium compounds and [[Grignard reagents]]). The initiation process involves the addition of a neutral (B:) or negative (B:-) [[nucleophile]] to the monomer.<ref name=Odian/>
The most commercially useful of these initiators has been the [[alkyllithium]] initiators. They are primarily used for the polymerization of styrenes and dienes.<ref name="Quirk"/>
