| dc.description.abstract | 本研究探討以回收聚碳酸酯(Polycarbonate, PC)為原料，利用胺解法製成反應含酚末端基之氨基甲酸酯中間體後，透過選擇適合之觸媒並搭配市售環氧單體，製成熱塑性聚合物環氧樹脂。將此具有羥基的中間體導入市售環氧單體，經由選擇適當催化劑控制反應中間體與環氧單體的反應性以避免交聯反應發生，並以一鍋二步法合成出熱塑性聚合物，進行結構與性質探討。本研究以氨基甲酸酯、苯酚及二級醇建立本研究環氧樹脂合成之模型，並以多種催化劑相互比較反應性，由核磁共振(Nuclear Magnetic Resonance Spectrometer, NMR)及微差掃描熱分析(Differential Scanning Calorimetry, DSC)證實透過磷系觸媒(三苯基膦烯)乙酸甲酯可有效控制反應中間體與環氧單體之反應選擇性，使環氧基選擇與苯酚進行反應的同時避免與氨基甲酸酯或二級醇產生反應，此結果證明磷系觸媒可適於熱塑性高分子之合成，並避免交聯副反應發生。 | zh_TW |
| dc.description.abstract | Chemical recycling of poly(bisphenol-A carbonate), (PC), into thermoplastic epoxy resin was studied by aminolysis of amine carbonylation reaction and a highly efficient and selective epoxy reaction ststem. Through using the epoxy curing catalyst with highly selectivity, the interim prepolymers can react with epoxy resin without any crosslinking effects between carbamate groups and epoxide. Via two-step one-pot process in this work, linear thermoplastic epoxy resin are prepared. Using carbamate, phenol and secondary hydroxyl group as model compounds, the epoxy curing mechanism is established by comparing three different kinds of catalyst system, tertiary-amine catalyst, phosphonium catalyst and non catalyst. Based on the nuclear magnetic resonance spectrometer (NMR) and differential scanning calorimetry (DSC) result, the choosing of methyl (triphenylphosphoranylidene)acetate (TPPA) as catalyst to control curing reaction between epoxide and carbamate groups could be achieved. This results prove that TPPA can be applied in the process of PC digested interim prepolymers epoxy reaction. | en |
