本研究以聚四甲基醚二醇、二甲醇基丙酸、異佛酮二異氫酸酯、三乙胺、乙二胺、及一種分散藍色染料一號透過預聚物混合法(prepolymer mixing process)製備水性聚氨酯及高分子染料，探討加入不同比例染料後的高分子染料官能基、機械性質、熱性質、光學性質變化與吸水性和色遷移。
由紫外線/可見光分光光譜儀及示差掃描熱量分析儀鑑定後，發現最大吸收波長產生改變、玻璃轉移溫度(Tg)往高溫移動，證明染料確實鍵入聚氨酯鏈，而在熱重損失分析儀顯示，染料加入水性聚氨酯後提升熱裂解溫度，在應用層面有廣泛的功能性。

A waterborne polyurethane covalently bonded anthraquinone dye chromophore was successfully synthesized via incorporating macromolecules disperse blue 1 into the polyurethane skeleton. Waterborne polyurethane and polymeric dyes synthesized by polytetrahydrofuran (PTMEG), dimethylolpropionic acid (DMPA), isophorone diisocyanate (IPDI), triethylamine ethylenediamine (TEA) and modified polymeric dye were prepared, which Disperse Blue 1 as the chain extender.
We will discuss change of functional groups, mechanical properties, thermal properties, optical properties and color migration.
Modified polyurethanes were identified by UV/vis/NIR spectrometers (UV)、 differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
