碩士 === 國立中興大學 === 化學工程學系 === 91 === 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.
