    • 本論文的研究方向主要探討Acrylic/WPU乳液Hybrid製程上，改變Acrylic之種類MMA、BA，藉由添加比例不同，進行合成上與物性上之研究探討。
    首先主要以預聚合法合成之m-TMXDI base 陰離子型水性PU(WPU，Polyurethane Dispersion)，藉由Hybrid 製程添加不同Acrylic種類：MMA(methylmethacrylate)、BA(Butyl acrylate)，合成出不同比例之乳液，利用GPC、FTIR、TGA、DLS來探討經過Acrylic改質後，各乳液合成性質之研究。由實驗結果發現，WPU/Acrylic 合成後，在熱性上對於硬鏈段影響較大，採用MMA、BA混合所合成之WPU乳液對於粒徑及耐熱都有較好之提升，並且採用疏水性Acrylic在聚合過程中，對於增加core-shell結構會有較多獲得的機會。
    接著對於物性分析上，主要選定以預聚合法合成之m-TMXDI base 陰離子型水性PU(WPU，Polyurethane Dispersion)，藉由Hybrid 製程添加不同Acrylic種類：MMA(methylmethacrylate)、BA(Butyl acrylate)，合成出不同比例之乳液，經過真空乾燥成膜後，對各成分之膜進行型態、機械性質、表面及斷面分析，型態方面利用動態黏彈分析儀(Dynamic Mechanical Analysis,DMA)了解分子間作用力，機械性質方面則以應力-應變曲線來測定，表面及斷面分析利用掃描式電子顯微鏡(Scanning Electron Microscope,SEM)來觀察。由實驗結果得知，經由MMA與BA適當比例添加，可以有效地增強WPU之機械性質，並且在DMA中也可以發現到儲存模式也相對地受到提升。表面及斷面的剝離及不平整性，可以利用BA的添加獲得更佳之表面、斷面性質。

    The study mainly discusses the characters of the composing and physics on the process of Acrylic/WPU latex Hybrid production by changing and adding different types of Acrylic such as methylmethacrylate and butyl acrylate in different proportion.
    The study focuses on that the m-TMXDI base anionic polyurethane dispersion which are synthesized by prepolymer mixing process are composed of the latex with different proportion by Hybrid production of adding different types of Acrylic:methylmethacrylate, butyl acrylate, and changing the structure of Acrylic with GPC, FTIR, TGA, DLS. According to the results of the research, after WPU/Acrylic are synthesized, they has not only more powerful affect on hard segment, but also better increase on particle size and heat-resistant when MPU is synthesized by mixing MMA and BA. Moreover, they are more probably to increase the structure of the core- shell during the process of hydrophobic Acrylic polymerization.
    The study emphasizes that the m-TMXDI base anionic polyurethane dispersion which are synthesized by prepolymer mixing process are composed of the latex with different proportion by Hybrid production of adding different types of Acrylic: methylmethacrylate and butyl acrylate, analyzes the types, mechanical characters, surface and section of different kinds of the panniculus after it is made in the condition of the vaccum and aridity, and uses Dynamic Mechanical Analysis to realize the effect on molecule. The mechanical characters are measured by the curve of stress and strain, and the analysis of the surface and section is observed by Scanning Electron Microscope. The experimental results show that adding MMA and BA in approximate proportion can gain the mechanical characters efficiently, and DMA can be found that the model of the deposition is increased corresponsively. The unglue and irregularity of the surface and section can add BA to get better characters.
