| 英文摘要 | A novel polyolefin-based elastomer of polyolefin-graft-poly(t-butylstyrene) is synthesized from styrene moieties via graft-from anionic living polymerization. The afforded elastomer comprises a soft poly(ethylene-t-1-hexene-t-divinylbenzene) segment and a hard poly(t-butylstyrene) [P(t-BS)] segment. The polymerization proceeds via complete lithiation of the pendent styrene groups (polyolefin elastomer) and subsequent graft anionic polymerization of 4-tert-butylstyrene (2000-10 000 g mol(-1)). The graft-from living anionic polymerization controls the grafting size with excellent efficiency by increasing the monomer concentration. To introduce functional groups into the polymer chain-end, vinyl isoprene units are introduced into the polyolefin-graft-poly(t-butylstyrene) anion to form polyolefin-graft-[poly(t-butylstyrene)-block-polyisoprene] via living block copolymerization. Subsequent graft chain-end multicarboxyl functionalization via thiol-ene "click" reactions introduces carboxyl groups into the [P(t-BS)] graft chain-end. The water contact angle of this multicarboxyl functionalized product exhibits a sharper decrement, which affects its hydrophilicity significantly. This process produces a novel, well-defined functionalized graft-type polyolefin-based elastomer with a high utility temperature and excellent mechanical properties. |
