Poly(terephthalamide) microcapsules can be reproducibly and easily prepared by interfacial polycondensation around emulsion droplets in water. Oil drops of cyclohexane/chloroform mixture stabilized with poly(vinyl alcohol) containing terephthaloylchloride serve as soft template. The interfacial polycondensation starts immediately after addition of an amine mixture (hexamethylenediamine/diethylenetriamine). Light and scanning electron microscopy prove the formation of capsules with size distribution in the range from a few up to 100 µm depending on particular composition of the reaction mixture. The morphology of the capsule wall is characterized by precipitated particles. If instead of pure organic solvents a reactive oil phase is used as template, the capsules can serve in subsequent reactions as templates for the synthesis of composite particles. In this way, styrene can be radically polymerized inside the capsule leading to composite capsules. The capsule morphology is determined by the partition of all components between all phases.

通过油滴软模板制作聚酰胺胶囊—1。胶囊壁的形态学研究

聚（对苯二甲酰胺）微胶囊可以通过在水中乳液液滴周围的界面缩聚可重复且容易地制备。用含有对苯二甲酰氯的聚（乙烯醇）稳定的环己烷/氯仿混合物油滴作为软模板。在加入胺混合物（六亚甲基二胺/二亚乙基三胺）后立即开始界面缩聚。光学和扫描电子显微镜证明了胶囊的形成，其尺寸分布范围从几个到 100 µm，具体取决于反应混合物的特定组成。胶囊壁的形态特征在于沉淀的颗粒。如果使用反应性油相代替纯有机溶剂作为模板，则胶囊可以在后续反应中用作合成复合颗粒的模板。通过这种方式，苯乙烯可以在胶囊内发生自由基聚合，从而形成复合胶囊。胶囊形态由所有相之间的所有组分的分配决定。
