This review focuses on poly(2-oxazoline) containing triblock copolymers and their applications. A detailed overview of the synthetic techniques is provided. Triblock copolymers solely based on poly(2-oxazoline)s can be synthesized by sequential monomer addition utilizing mono- as well as bifunctional initiators for the cationic ring-opening polymerization of 2-oxazolines. Crossover and coupling techniques enable access to triblock copolymers comprising, e.g., polyesters, poly(dimethylsiloxane)s, or polyacrylates in combination with poly(2-oxazoline) based segments. Besides systematic studies to develop structure property relationships, these polymers have been applied, e.g., in drug delivery, as (functionalized) vesicles, in segmented networks or as nanoreactors.

这篇综述集中在含聚（2-恶唑啉）的三嵌段共聚物及其应用上。提供了合成技术的详细概述。仅基于聚（2-恶唑啉）的三嵌段共聚物可以通过使用单官能引发剂和双官能引发剂进行顺序的单体加成而合成，以用于2-恶唑啉的阳离子开环聚合。交叉和偶联技术使得能够获得包含例如聚酯，聚（二甲基硅氧烷）或聚丙烯酸酯与基于聚（2-恶唑啉）的链段组合的三嵌段共聚物。除了开发结构性质关系的系统研究以外，这些聚合物还被应用于例如药物递送，（功能化）囊泡，分段网络或纳米反应器中。
