摘　　要：用3,3’,4,4’ 二苯甲酮四羧酸二酐分别与1 (3 氨基苯基) 3 (4 氨基苯基) 2 丙烯 1 酮(光敏性二胺Ⅰ)和 3,3’,5,5’ 四乙基 4,4’ 二氨基二苯甲烷(光敏性二胺Ⅱ),经溶液聚合、化学亚胺化,制备了一类新型可溶性的光敏聚酰亚胺。该合成方法简便,分子量容易控制,起始原料价廉易得,产品纯度与收率高。TGA、UV、GPC等研究结果表明所制备的树脂曝光波长能与工业Ⅰ线匹配使用,具有良好的耐热性能与感光性能。A novel photosensitive diamine monomer containing chalone moiety was prepared. The synthesis and properties of novel soluble photosensitive polyimide (PSPI) based on photosensitive diamines and 3,3',4,4'-benzophenonetetracarboxylic dianhydride are studied by means of TGA, UV and GPC analysis. This synthetic method has the advantages of simpleness, cheapness, high yield and purity. The molecular weights of resins are easy controlled and their exposal wavelengths were suited for I-line of industry with high performance of heat-resistance and sensitization.
