摘要: 
In this paper, using two kinds of diamines (PO and EO) to polymerize two kinds of polymers. One is Amine-Terminated Mannich Oligomers (AMO), the other is Amine-Terminated BPA Epoxy Oligomers(AEO), and go a step further to use these two polymers to intercalate montmorillonite (MMT). Comparing the mechanism with intercalation and exfoliation, and using XRD to measure MMT's basal-spacing.
In part one, two kinds of wide molecular weight copolymers were prepared from the reaction of poly(oxyalkylene)diamine, p-cresol and formaldehyde. By the acidification of the end group amine of the copolymers, the quarternary amine salt can exchange with the Na+ in the layer silicate galleries. D2000 AMO is hydrophobic can enlarge basal-spacing to 50Å. Furthermore, by controlling the HCl amount addition, the one-step exfoliation will observe by zig-zag conformation. In the other hand, ED2001 AMO is hydrophilic. By treating with different equivalents of hydrochloric acid, and the basal-spacing is still 18Å.
In part two, two kinds of wide molecular weight copolymers were prepared from the reaction of poly(oxyalkylene)diamine and epoxy. By the acidification of the end group amine of the copolymers, the quarternary amine salt can exchange with the Na+ in the layer silicate galleries. D2000 AEO is hydrophobic can enlarge basal-spacing to 56Å. In the other hand, ED2001 AEO is hydrophilic. By treating with different equivalents of hydrochloric acid, and the basal-spacing is still 18Å.

本論文是利用含有PO與EO鏈段的兩種diamine以聚合形成兩種高分子Amine-Terminated Mannich Oigomers (AMO)與Amine-Terminated BPA-Epoxy oligomersN(AEO),並進一步利用這兩種高分子來插層蒙脫土,比較脫層與插層的機制,並利用XRD來測定蒙脫土的層間距。以下將分為兩部分論述:
(1) 以Jeffamine® Amines D2000 與 ED2001分別與p-cresol, formaldehyde 合成兩個性質不同的寬廣分子量高分子 (AMO),將這兩個高分子經酸化後成為四級胺鹽,與蒙脫土之層間陽離子進行陽離子交換反應。由於D2000 AMO是比較親油性,所以可以將層間距撐開到61Å,再經由控制不同比例的酸化量,藉由Zag-Zig的力量,使得蒙脫土可以達到一步脫層。而ED2001 AMO是比較親水性,所以不管如何控制酸化量,ED2001 AMO會跟親水的蒙脫土層間產生鍵結,而躺在蒙脫土層間,造成層間距仍然是18 Å左右。
(2) 另外以Jeffamine® Amines D2000 與 ED2001分別與Epoxy (BE-188)進行聚合反應而得到兩個性質不同的寬廣分子量的高分子 (AEO),將這兩個高分子經酸化後成為四級胺鹽,與蒙脫土之層間陽離子進行陽離子交換反應。由於D2000 AEO是親油性,所以可以將黏土的層間撐開,最大可以到56Å而ED2001 AEO是比較親水性,所以不管如何控制酸化量,ED2001 AEO會跟親水的蒙脫土層間產生鍵結,而躺在蒙脫土層間,造成層間距仍然是18 Å左右。
