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.
