摘要

<正> The use of living

alkyllithium-initiated anionic polymerization to prepare chain-end functionalized polymers and heteroarm

star-branched polymers is discussed. The scope and limitations of specific termination reactions with a variety of electrophilic species are illustrated for carbonation

hydroxyethylation

and sulfonation. The methodology of using substituted 1

1-diphenylethylenes to provide a general

quantitative functionalization procedure is outlined and illustrated with examples of amine and phenol end-functionalization. A methodology is described for the synthesis of functionalized

star-branched copolymers with compositionally heterogeneous arms of controlled molecular weight and narrow molecular weight distribution using 1

3-bis（1-pbenylethenyl） benzene.
