New multifunctional coupling agents with one 2-oxazoline group, one oxazinone group, and one allyl ether group were prepared.模型反应表明，在反应挤出条件下，2-恶唑啉基和恶嗪酮基分别与羧基和氨基选择性反应。 The allyl ether group remained unaffected under the reaction conditions chosen.作为模型反应，偶联剂与 11-氨基十一烷酸的转化导致烯丙氧基官能化聚（酯酰胺）的形成。该反应可以逐步进行，其中氨基的反应在110℃的溶液中进行，而羧基的反应在220℃的熔体中进行。此外，还描述了使用偶联剂制备每个链端具有一个恶唑啉基团和一个烯丙基醚基团的遥爪聚丙二醇。 © 2003 Wiley Periodicals, Inc.

New multifunctional coupling agents with one 2-oxazoline group, one oxazinone group, and one allyl ether group were prepared. It was shown by means of model reactions that under the conditions of reactive extrusion, the 2-oxazoline group and the oxazinone group reacted selectively with carboxylic groups and amino groups, respectively. The allyl ether group remained unaffected under the reaction conditions chosen. As a model reaction, the conversion of the coupling agents with 11-aminoundecanoic acid resulted in the formation of an allyloxy-functionalized poly(ester amide). The reaction could be performed stepwise, in the course of which the reaction of the amino group proceeded at 110 °C in solution, whereas the reaction of the carboxylic group was performed in the melt at 220 °C. Furthermore, the utilization of the coupling agents for the preparation of telechelic poly(propylene glycol) with one oxazoline group and one allyl ether group on each chain end was described. © 2003 Wiley Periodicals, Inc.
