本研究分別以甲基丙烯酸甲酯(methyl methacrylate，MMA)、甲基丙烯酸乙酯(ethyl methacrylate，EMA)、甲基丙烯酸第三丁酯（tert butyl methacrylate，tBMA)及甲基丙烯酸羥乙酯(hydroxy ethyl methacrylate，HEMA)與鄰苯二甲酸二丙烯酯（diallyl phthalate，DAP）及己二酸二乙烯酯（adipic acid divinyl ester，AADE）經總體聚合的方法製備八種壓克力共聚合物。
本研究以傅立葉紅外線光譜儀（FT-IR）鑑定共聚物之結構。在共聚合物光學性質以阿貝計(Abbe)測試其對波長為589nm的折射率及紫外光/可見光譜儀(UV-Vis)在可見光區的穿透性。在熱性質方面以微差熱掃描卡計(DSC)、熱重損失分析儀(TGA)及動態機械分析儀(DMA)量測玻璃轉移溫度(Tg)、熱裂解溫度及機械性質，並利用二種熱裂解動力學模式(Kissinger, Ozawa)，求得共聚合物之熱裂解活化能。
由研究結果顯示，在添加AADE及DAP改質之共聚合物，其折射率皆有明顯上升，在共聚合物中含有DAP苯環結構之共聚合物其折射率提升較佳。由DSC結果顯示，共聚合物之玻璃轉移溫度，於DAP及AADE最佳改質添加量1~5wt%時，均可提升Tg約10~20℃。且在MMA/AADE共聚合物中添加改質含量1wt%時，具有最佳玻璃轉移溫度(123℃)。由TGA結果顯示，分別添加DAP及AADE改質之共聚合物，其熱安定性有明顯提升的效果。在熱裂解溫度及裂解活化能之結果顯示MMA、EMA及HEMA共聚合物中，隨著添加DAP、AADE改質含量的增加，其熱裂解溫度及裂解活化能均有明顯上升之趨勢。此外，由TGA結果得知添加AADE改質之共聚合物其熱安定性較添加DAP改質之共聚合物為佳。

Eight types of copolymers based on methyl methacrylate (MMA), ethyl methacrylate (EMA), tertbutyl methacrylate (tBMA) and hydroxyl ethyl methacrylate (HEMA) were prepared via bulk polymerization with the modifiers which were diallyl phthalate (DAP) and adipic acid divinyl ester (AADE), respectively.
The structures of these synthesized copolymers were characterized by IR spectra. The optical properties and thermal properties of synthesized copolymers were investigated by ultraviolet/visible (UV-Vis), Abbe refractometer, differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA) and dynamic mechanical analyzer (DMA). The activation energies of thermal degradation for the copolymers were calculated from Ozawa’s and Kissinger’s method, respectively.
The results of this study suggested that copolymers that contained DAP and AADE respectively increased the refractive index. The refractive indexes for the DAP-containing copolymers were higher than those AADE-containing copolymers. The results of DSC for the synthesized copolymers showed that contained 1~5 wt% of modifier in the copolymer were found to increase the value of Tg (10~20℃). Furthermore, the MMA/AADE copolymer that contained 1wt% of AADE exhibited a high value of Tg at 123℃. The results of TGA for the synthesized copolymers showed that the thermal stability of copolymer that contained modifier was enhanced. The temperature and activation energies of thermal degradation for the copolymers increased upon increasing the modifier content in copolymers of MMA, EMA and HEMA system. Additionally, the thermal stability for the AADE-containing copolymers was better than those DAP-containing copolymers.
