摘　　要：采用自合成的端羟基聚乳酸(PLAOH)、甲苯二异氰酸酯(TDI)、二羟甲基丙酸(DMPA)等原料合成了阴离子型可生物降解的水性聚氨酯乳液,讨论了羧基含量(-COOH％)对乳液性能的影响。结果表明:随着-COOH％增加,乳液平均粒径变小,乳液稳定性增加,乳液的粘度也明显增加。A kind of biodegradable aqueous polyurethane emulsion was synthesized by self-synthesizing PLAOH, TDI, DMPA, and some other materials. The effects of the content of ——COOH（——COOH% ） on the performance of APU emulsion were studied. The results showed that while ——COOH% increased, the average particle size of the emulsion decreased, the stability of the emulsion increased, and the viscidity of the emulsion also increased.
