摘要
本研究用α，α′—二羟甲基丙酸和Ｎ，Ｎ—二羟乙基对苯甲酸酰胺两种分子结构差异较大的阴离子扩链剂，制备出一系列水乳型聚氨酯，探讨了所用亲水性扩链剂的结构对制备的水乳型聚氨酯贮存稳定性和成膜物耐水性等的影响。
Aqueous dispersions of polyurethane containing different anionic hydrophilic segments were prepared from dimethylol propionic acid O-phthalic acid-bis-N,N (ethylol) amide as anionic hydrophilic extender. The effects of structure of the extenders on storage stability of the dispersions, water uptake of the film were determined.
