阴离子聚氨酯乳液的粒径及粒子形态的研究

Study on Particle Size and Morphology of the Anionic Polyurethane Emulsion

讨论了用二羟甲基丙酸制备阴离子聚氨酯乳液，二羟甲基丙酸的量，反应程度，扩链剂的用量对乳液的稳定性、粒径大小和分布及粒子形态的影响。

The anionic polyurethane emulsion presented here was prepared with Dimethylol propionic acid (DMPA), and its stability, particle size and morphology were determined. The effect of the amount of DMPA, extent of reaction and the amounts of extender were dissussed on propertis of its emulsion-
