采用含硝基烷烃的伯胺引发剂对α-氨基酸-羧基氢化物单体进行开环聚合，并进行末端转化，采用两步法合成了一种腈-氧化物功能化多肽。形成的功能化肽与含双键橡胶进行了高效的无催化剂接枝反应。
A nitrileN-oxide-functionalized polypeptide was synthesized by a two-step method involving the combination of ring-opening polymerization of an α-amino acidN-carboxyanhydride monomer using a primary amine initiator containing a nitroalkane group and a subsequent terminal conversion. The catalyst-free grafting reaction of the formed functionalized peptide with rubbers containing double bonds was achieved with high efficiency.
