碩士 === 國立臺北科技大學 === 化學工程研究所 === 97 === This thesis consists of two parts. In Chapter 1, we synthesized novel polyimides containing 1,2,4-triazole and triphenylamine groups. In Chapter 2, we synthesized poly(ether imide)s in which main chain contains triazole group and side chain was carbazole group or triphenylamine group. The thermal properties, optical properties and solubility of the polymers were investigated and discussed. 　　The obtained polyimides and poly(ether imide)s all exhibited good thermal stability with 5% loss weight temperature higher than 400℃ in nitrogen, and the glass transition temperatures were about 250-300℃. The polyimides with triphenylamine group in the main chain had higher glass transition temperature and better solubility than the polyimides with triazole group in the main chain. The solubility with poly(ether imide)s were better than analogous polyimides. The UV-vis maxium absorption exhibited near 280nm for polymers with triphenylamine group in the main chain and polymers with triazole group in the main chain. The maxium photoluminescence emission near 400nm for polymers with triphenylamine group in the side chain and near 350nm for polymers with carbazole group in the side chain.
