제목 | Synthesis of Amine end-capping St/DVB particle using Anionic Dispersion polymerization |
초록 | Synthesis of styrene/DVB particle by anionic dispersion polymerization in n-hexane using poly(styrene-b-butadiene) block copolymer as the stabilizer. The St/DVB particles were washed by n-hexane for several times, then dried overnight. The controlled formation of polymer brushes polybutadiene and polyisoprene graft from St/DVB cores were prepared by living anionic surface initiated polymerization(LASIP). Immobilized double bonds on the surface of St/DVB particles were initiated using sec-buthyllitium(BuLi) in the presence of N,N,N’,N’-tetramethylethylenediamine(TMEDA), and the sequence of amine-functionalized. After initiation of St/DVB particle were end-capping with 4,4-bis(diethylamino)benzophenone. The characteristic of this aromatic amine end-capping particles were confirmed by infrared spectroscopy(IR), scaning electron microscope(SEM) and elemental analaylsis(EA). |
