    Abstract: 本實驗以水性PU樹脂之改質為主要研究對象。目前的水性PU樹脂,除了樹脂的性質穩定性需要改進外,它的應用性質尚無法取代傳統之溶劑型PU,是因為水性PU樹脂的分子量較低並且缺乏架橋型網狀結構。此實驗將利用水性的聚胺基甲酸酯(Polyurethane,簡稱PU),和GMA-共聚物乳液進行共摻混,並另外加入多元次乙亞胺架橋劑,增加其架橋密度,以達到水性PU改質的目的,並探討其一些物理性質。
    Modificantions of aqueous-based polyurethanes are the major objectivesof this report. Besides the stability of current aqueous-basedpolyurethane dispersions needed to be improved, their applicationproperties were not compatible with conventional solvent-basedpolyurethanes yet. Due to their low molecular weight and lesspolymeric cross-linked networks. Several aziridinyl cross- linkingagents were synthesized and worked as "latent curing agent" ofaqueous-based PU dispersions.
