摘要: 对二苯胺-4-重氮盐(DS)、邻-甲氧基二苯胺-4-重氮盐(MDS)和N-甲基-间硝基二苯胺-4-重氮盐(NDS)及它们的重氮树脂(DR,MDR,NDR)在水溶液中的光,热分解研究表明,这些重氮盐和树脂的光分解性质,即感光灵敏性差别不大,而热分解性质,即热稳定性差别很大.MDS的热稳定性最好.固相膜中3种树脂的光分解亦差别不大,但N-甲基-间硝基二苯胺-4-重氮树脂(NDR)固相膜的热稳定性出乎预料地好.从疏水性的角度对NDR固相膜突出的热稳定性作了初步解释.

Abstract: The photo and thermal decomposition of three diphenylamine-4-diazonium salts: DS, MDS, NDS and the corresponding diazoresins DR, MDR, and NDR were investigated in water and in solid films. It was found that the photo-decomposition is no obvious difference in aqueous solution for various salts and resins, but the thermal decomposition is different remarkably. The methoxy substituted diazonium salt(MDS) and resin(MDR) possess higher thermal stability than that of DS, NDS and their resins. In the case of solid films the NDR exhibits superior thermal stability due to its high hydrophobic characteristic.

Key words: diphenylamine-4-diazonium salt, diazoresin, photo and thermal decomposition
