| Abstract: | A novel well-defined comb-like ionomer with cations was synthesized by the combination of living anionic polymerization and
atom transfer radical polymerization (ATRP). The synthetic approach involves the coupling reaction of polystyrene (PS) backbone
bearing 1,1-diphenylethene (DPE) pendant groups with living polystyryllithium (PSLi), subsequent amine functionalization of
the resulting 1,1-diphenylmethyl anions with 3-dimethylaminopropyl chloride (DMAPC), and quaternization of tertiary amino
groups with hydrochloric acid. The comb-like ionomer was characterized by 1H NMR, IR, GPC measurements and end-group titrition. |
