Developments on the synthetic techniques of alicyclic dianhydrides and polyimides
碩士 === 國立臺灣科技大學 === 材料科學與工程系 === 105 === In this study, we use new synthetic route to prepare two alicylic dianhydrides (4arH,8acH)-decahydro-1t,4t:5c,8c-dimethanonaphthalene-2c,3c,6c,7c-tetracarboxylic-2,3:6,7-dianhydride [DNDA(xn), Exo, Endo] and (4arH,8acH)-decahydro- 1t,4t:5c,8c-dimethanonaphtha...
