软段含离子基团的阴离子型水性聚氨酯胶粘剂的研究(Ⅰ)——软段结构的影响

Study on anionic aqueous polyurethane adhesives based on polyols containing different ionic groups(Ⅰ)--the effects of soft segment structure

以含有不同离子基团的聚酯多元醇为软段,采用丙酮法合成了一系列水性聚氨酯乳液。研究了不同离子基团的聚酯多元醇和不同软段结构对其干膜物理机械性能和吸水率的影响。

Some anionic aqueous polyurethane dispersions were prepared by acetone method. The effects of polyols type and polyols containing different ionic groups on physical mechanical properties of dry films and water absorption were studied.
