    • 使用離子性高分子PEL (PPO與PEO共聚合) 摻合各種不同比例之Coronate，並藉由同時式聚合反應方式與環氧樹脂組成抗靜電塗料之配方，另外利用壓克力感壓膠和調整catalyst含量的多寡來製備薄膜貼合之黏著劑，兩者經由實驗結果之探討，從當中選擇最適當材料配比，以製備出最佳之抗靜電性之感壓膠保護膜。
    在壓克力感壓膠部分，添加不同觸媒的含量，使聚合反應不斷進行，經由分子量大小的控制及軟硬度之調整，可以改變初期黏著力、黏著力及凝集力，以得到理想之壓克力黏著劑。實驗結果發現，隨著catalyst添加量愈多，黏著強度會隨之變小，另外添加catalyst的含量愈少，剝離後之殘膠量會隨著減少的趨勢。
    在抗靜電塗料方面，添加愈多的Coronate含量，會使表面電阻、硬度、對薄膜的附著力及抗拉強度隨著提高，實驗結果為85 PHR時為最大，但在95 PHR時，由於Coronate與PEL架橋反應過剩，存留於離子性高分子中，使附著力、硬度及抗拉強度反而減少，而表面電阻值也減少到109 Ω/square，造成導電率增加，另外透光率在可見光550nm 時，都大於 80%。綜合以上結果顯示，本論文所製備的抗靜電性之感壓膠保護膜應具有相當潛力可應用於偏光板產業中。

    The ionic polymer PEL (PPO and PEO copolymer) and Coronate was blended in various proportion to the PEL, and epoxy resin were blended by the method of simultaneous polymerization to compose anti-static coating prescription. In addition, acrylic pressure sensitive adhesive used catalyst’s quantity to adjust film’s adhesion force. According to the experimental results, we can choose appropriate material prescription to prepare best anti-static and adhesive protection film.
    In acrylic PSA part, The catalyst was blended in various proportion to promote generation free radicals, the free radical polymerization taking place at the presence of Hardener and continue agitating. The amount of hardener added in the reaction can affect the size of molecule weight, the use of different catalyst’s quantity and its ratio can affect the hardness of acrylic polymer, the Tack, Adhesion and Cohesion of acrylic adhesion can be changed by controlling the molecule weight and hardness. Thus the acrylic adhesion with required properties can be obtained. To modify the acrylic adhesion is the purpose of this study. According to the experimental results, the adhesion force would be improved with increasing Coronate. Besides, the residual glue would be reduced with decreasing Coronate.
    In anti-static coating part, the surface resistance、hardener、adhesive force and tensile strength would be improved with increasing Coronate. While the Coronate content was 85PHR, all would go to a maximum. However, 95PHR would make all decrease and surface resistance was downed to 109 Ω/square. Because coronate generated crosslinking reaction with PEL, it made coronate surplus to retain ionic polymer. Furthermore, Film transmittance had above 80% on the 550nm. In conclusion, this study for protection Film will have potential application in polarizer industry.
