Controlled growing of Polydiene brushes by Living Anionic Polymerization on the Poly(styrene-co-divinylbenzene) Particle Surfaces |
| 초록 |
Polydiene brushes on the Poly(styrene-co-divinylbenzene) particle surfaces were synthesized by means of Living Anionic Polymerization with sec-BuLi as an initiator and TMEDA as a polar additive. 83% graft efficiency was obtained with 90% yield by removal of excess sec-BuLi. 5.41ⅹ106chains/μm2 graft density was confirmed by control of the concentration of TMEDA. The surfaces of the synthesized particles with polydiene brushes were analyzed by SEM. The Mw was measured using GPC and the microstructures was characterized by 1H-NMR. |
