本文综述了用于制备珠状树脂、干粉和高固体分散体的悬浮、分散和界面缩聚工艺的概况。所涉及的聚合物系统包括聚酰胺、聚酯、聚碳酸酯、聚氨酯、酚醛树脂和脲醛树脂。概述了非均相缩聚过程的基本特征，并讨论了悬浮、分散和界面缩聚中颗粒形成的不同机理。还简要介绍了进料比、液滴/颗粒稳定剂和搅拌器速度等制造参数对产品特性的影响。
This review presents a general picture of suspension, dispersion, and interfacial polycondensation processes employed for the preparation of beaded resins, dry powders, and high solid dispersions. The polymer systems covered include polyamides, polyesters, polycarbonates, polyurethanes, and phenol-formaldehyde and urea-formaldehyde resins. Basic features of heterogeneous polycondensation processes are outlined, and different mechanisms of particle formation in suspension, dispersion, and interfacial polycondensation are discussed. Effects of manufacturing parameters such as feed ratio, droplet/particle stabilizer, and stirrer speed on product characteristics are also briefly covered.
