Anionic Polymerization Anionic Polymerization -

anionic addition polymerization wikipedia - anionic addition polymerization is a form of chain growth polymerization or addition polymerization that involves the polymerization of vinyl monomers with strong electronegative groups this polymerization is carried out through a carbanion active species like all chain growth polymerizations it takes place in three steps chain initiation chain propagation and chain termination, living anionic polymerization wikipedia -
