以三嗪為主體高分子聚合物：合成與物性探討

在論文中，合成出以三嗪分子為主體的二氯與二胺單體。不同官能基所合成的三嗪分子單體經由聚合反應可得到聚脲與聚醚高分子材料。合成高分子藉由熱重分析儀與示差掃描熱量分析儀的量測可以得知具有良好的熱穩定性。高分子所形成的薄膜在350nm以上具有好的透光性。其中芳香族的高分子具有最佳的熱穩定性(裂解溫度為於405 ℃)。高分子PU-DMPA-MDI對於酸最為敏感，當pH小於5時就會分解的現象出現。含有脂肪族的高分子材料具有最佳的生物相容性，與玻璃的相似度高達95%。藉由以上的實驗，證明含有三嗪分子高分子材料具有熱穩定、酸分解性與生物相容性等特性。

This thesis is to report the synthesis of triazine-based compounds which contain the dichloride and diamine moieties. Effective approaches were employed to synthesize monomers containing various functional group for preparing polyureas and polyethers. Polymers show good thermostability by Thermogravimetric Analysis and Differential Scanning Calorimeter. The film from polyureas with aliphatic functional groups have good transmittance above 350 nm visible light. Polymers with aromatic functional groups have the good thermo stability (decmposition at 405℃). PU-DMPA-MDI is sensitive to acid, decomposing at pH<5. Polyureas with aliphatic functional groups also show the good biocompatibility (<95%). The triazine-based polymers are proved to be thermo-stable, acid-degradable and biocompatible materials.
