摘要

A series of 3-arm ABC and AA'B and 4-arm ABCD

AA'BC and AA'A"B heteroarm star polymers comprising one poly(4-methylphenyl vinyl sulfoxide) segment and other segments such as polystyrene

poly(α-methylstyrene)

poly(4-methoxystyrene) and poly(4-trimethylsilylstyrene) were synthesized by living anionic polymerization based on diphenylethylene (DPE) chemistry. The DPE-functionalized polymers were synthesized by iterative methodology

and the objective star polymers were prepared by two distinct methodologies based on anionic polymerization using DPE-functionalized polymers. The first methodology involves an addition reaction of living anionic polymer with excess DPE-functionalized polymer and a subsequent living anionic polymerization of 4-methylphenyl vinyl sulfoxide (MePVSO) initiated from the in situ formed polymer anion with two or three polymer segments. The second methodology comprises an addition reaction of DPE-functionalized polymer with excess sec-BuLi and a following anionic polymerization of MePVSO initiated from the in situ formed polymer anion and 3-methyl-1

1-diphenylpentyl anion as well. Both approaches could afford the target heteroarm star polymers with predetermined molecular weight

narrow molecular weight distribution (Mw/Mn 1.03) and desired composition

evidenced by SEC

1H-NMR and SLS analyses. These polymers can be used as model polymers to investigate structure-property relationships in heteroarm star polymers.
