| 英文摘要 | the thiol-halogen click chemistry between halogenated isotactic polypropylenes (ipps) and thiols was systematically investigated for the first time. the order of copolymer reactivity can be summarized as iodinated >> brominated > chlorinated ipp, while for different thiols, the reactivity depended on not only the acidity of the sulfhydryl but also the competition of the polar group in the thiols with -sh to participate in the nucleophilic substitution reaction. in this case, various polar groups including hydroxyl, ester, aryl, thiazolyl and amino have been successfully introduced into ipp in a quantitative way, by employing iodinated ipp as the highly reactive intermediate. the content of polar groups in the high molecular weight functional ipps (m-w > 100 kg mol(-1)) could be tuned in a wide range of 0-11 mol%. more notably, this new strategy offers an effective route to prepare the well-defined graft copolymer ipp-g-pcl from the halogen functionalized ipp and poly(e-caprolactone)s with highly reactive -sh end (pcl-phsh). initiated by the resulting hydroxyl-containing ipp, ring-opening polymerization of l-lactide (lla) provided another kind of graft copolymer, ipp-g-plla. |
