报道了双(N-羰基氮丙啶)聚合形成聚酰胺共聚物。对苯二氮丙啶 (TP-Az) 源自消费后的 PETE，与多种双亲核试剂（包括二羧酸、二酚和二硫化物）反应，分别形成聚（酰胺酯）、聚（酰胺醚）或聚（酰胺硫化物）。脂肪族己二酰氮丙啶(AD-Az)和2-甲基取代的TP-MeAz的逐步聚合反应与TP-Az的聚合反应相似。 TP-Az、AD-Az 和TP-MeAza 的聚合反应在温和条件下和露天进行，条件与许多官能团相容。例如，衣康酸（含有亚乙烯基）和 d-酒石酸（含有二醇）均可与 TP-Az 共聚，无需保护基化学。
The polymerizations of bis(N-carbonyl aziridine)s to form polyamide copolymers are reported. Terephthalaziridine (TP-Az), derived from postconsumer PETE, reacts with a variety of dinucleophiles, including dicarboxylic acids, diphenols, and disulfides, to form poly(amide ester)s, poly(amide ether)s, or poly(amide sulfide)s, respectively. The step-growth polymerization of the aliphatic adipoyl aziridine (AD-Az) and the 2-methyl-substitutedTP-MeAzmirrors that ofTP-Az. The polymerizations ofTP-Az, AD-Az, andTP-MeAzare performed under mild conditions and open air, conditions that are compatible with many functional groups. As examples, both itaconic acid (containing a vinylidene group) andd-tartaric acid (containing a diol) copolymerize withTP-Azwithout the need for protecting group chemistry.
