"In polymer chemistry, anionic addition polymerization is a form of chain-growth polymerization or addition polymerization that involves the polymerization of monomers initiated with anions. The type of reaction has many manifestations, but traditionally vinyl monomers are used. Often anionic … See more As early as 1936, Karl Ziegler proposed that anionic polymerization of styrene and butadiene by consecutive addition of monomer to an alkyl lithium initiator occurred without chain transfer or termination. Twenty … See more Initiators are selected based on the reactivity of the monomers. Highly electrophilic monomers such as cyanoacrylates require only weakly nucleophilic … See more Living anionic polymerization is a living polymerization technique involving an anionic propagating species. Living anionic … See more • Cowie, J.; Arrighi,V. Polymers: Chemistry and Physics of Modern Materials; CRC Press: Boca Raton, FL, 2008. • Hadjichristidis, N.; Iatrou, H.; Pitsikalis, P.; Mays, J.
