摘　　要：采用相分离法对尼龙溶液在发生相分离过程中的影响因素进行了研究。包括聚合物溶液浓度、凝聚剂的用量及加入速度、分散稳定剂的用量、搅拌速度等，获得了较优的制备工艺条件。所制备的尼龙粒子分布较均匀，表而粗糙，存在较多孔洞，粒子与粒子之间的分散性较好，无相互粘连现象。In this paper, the influence factors of nylon particles by phase separation method were researched, including polymer solution concentration, coagulant dosage and adding speed, dispersant dosage, and mixing speed etc. Then, better preparation conditions were obtained. The nylon particles prepared under this condition had ahnost uniform size distribution, rough surface and more cavitations. These particles had better dispersion and no mutual adhesion phenomenon.
