"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 initiators, such as amines, phosphines, or even halides. Less reactive monomers such as … See more Block copolymers Synthesis of block copolymers is one of the most important applications of living polymerization as it offers the best control over structure. The See more Two broad classes of monomers are susceptible to anionic polymerization. Vinyl monomers have the formula CH2=CHR, the most important are styrene (R= C6H5), butadiene (CH=CH2), and isoprene (R = C(Me)=CH2). A second major class of … See more Propagation in anionic addition polymerization results in the complete consumption of monomer.
