碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 103 === In this thesis we investigated the reaction phenomenon of bisphenol A with m-cresol and 3,4-dimethylphenol, respectively. We expected to get ladder monomers X-1, X-2 and spiro monomers SC-1, SC-2, respectively by the reaction. The result suggested that temperature, ratio of reactants, amount of catalyst and control of time were the important factors that determined the accessibility to the spiro monomers. The obtained monomer would be applied in the preparation of high performance polymer after functionalization. Polyamide made by ladder monomer XA-1 exhibit excellent thermal properties, while the reactivity of SCA-1 monomer would be investigated in the thesis. SI monomer, the by product of the monomer''s reaction, could be made into polyether sulfone, and its properties would be compared to that made of bisphenol A in the thesis.
