摘要
制备出了分子链上同时带有酸、碱基团的两性聚氨酯 (APU) ,该两性聚氨酯在酸碱介质中均能形成稳定的纳米水分散液。同时还测定了APU的等电点和水分散液中APU分子链上可离子化基团的含量 ;实验结果还表明
An amphoteric polyurethane(APU) with acid(—COOH) and alkaline(—N(CH 3) 2) groups on the side chains had been prepared by self\|emusifying methods. This kind of amphoteric polyurethane (APU) can form stable nanometer sized waterborne dispersions in acid or alkaline media. The studing results indicated that pH values affect the particle sizes and stability of the APU waterborne dispersions greatly.\;
