分別改變基丙烯酸-2-基乙基酯、丙烯基縮水甘油醚、異氰酸鹽、Silicone dioxide的濃度所合成的水性PU接著劑，的分子結構已經紅外線光譜證實。
實驗結果顯示水性PU接著劑分子平均粒徑以及黏度會隨著丙烯基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單體濃度的增高而逐漸增大，這是因為PU壓克力混成樹脂分子間與水分子間的作用力增強，使得分子的自由體積變大，結果導致水性PU接著劑之粒徑和黏度變大。
水性PU混成樹脂接著劑溶液之表面張力，會隨著烯丙基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單體濃度的增高而逐漸變大，這是因為吸附在水溶液表面上的非極性基受溶液內PU 分子上極性基的作用而排列較整齊之故。
水性PU混成樹脂接著劑薄膜之硬度，會隨著丙基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單體濃度增高而變硬，已達到一個鉛筆HB的硬度。這可能是因為分子排列較整齊之故。
水性PU混成樹脂接著劑薄膜之光澤度，會隨著烯丙基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單體濃度壓克力單體濃度的增高而逐漸變小，這是因為薄膜表面上的分子排列較不整齊之故。
水性PU混成樹脂接著劑薄膜之拉應力(tensile strength)，會隨著丙烯基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單體濃度的增高而逐漸增大，這是因為水性PU接著劑分子本身的作用力增強，使得水性PU混成樹脂接著劑的架橋能力變強之故。相反地，水性PU接著劑薄膜之伸長率(elongation)，會隨著丙烯基縮水甘油醚和甲基丙烯酸-2-基乙基酯壓克力單濃度的增高而逐漸下降，這是因為水性PU 樹脂分子自身的作用力較強，而使得混成樹脂薄膜的伸長率變小之故。
The reaction of toluene diisocyanate with polyester and other additives to form the conformation of water- soluble polyurethane (PU) and acrylics hybrid resin adhesive molecule has been proven by IR spectra. Experimental results showed that both viscosity and average particle size for water- soluble PU/acrylics hybrid resin adhesive increased with increasing concentration of Allyl glycidyl ether and 2-hydroxyethyl methacrylate, respectively. This maybe due to increased free volume resulting from the intermolecular interaction between the water-soluble PU/acrylics hybrid resin molecules themselves and between this hybrid resin molecules and water molecule. Thus, both average particle size and viscosity increased. In aqueous solution, the surface tension of the water- soluble PU/acrylics hybrid resin increased with increasing concentration of the water- soluble PU/acrylics hybrid resin concentration of Allyl glycidyl ether and 2-hydroxyethyl methacrylate , respectively .The reason because the hydrophobic groups of the water- soluble PU/acrylics hybrid resin adsorbed at the surface of water became even more ordered.
The hardness of the film made by the water- soluble PU/acrylics hybrid resin increased with increasing concentration of Allyl glycidyl ether and 2-hydroxyethyl methacrylate, respectively, as a result of the arrangement of the molecules becoming more ordered. The gloss of the film made by the water- soluble PU/acrylics hybrid resin decreased with increasing concentration of Allyl glycidyl ether and 2-hydroxyethyl methacrylate, respectively, as a result of the arrangement of the molecules becoming less ordered.
