英文摘要: Polyimides containing perfluorocyclobutane rings were synthesized from a new diamine 1, 2, 3, 3, 4, 4-hexafluoro-1, 2-bis (4-aminophenoxy) cyclobutane with three dianhydrides, namely bicyclo [2.2.1] octane-2, 3, 5, 6-tetracarboxylic 2, 3, 5 1 6-dianhydride (BHDA), biphenyltetracarboxylic dianhydride ( BPDA) and benzophenone-3, 3', 4,4'-tetracarboxylic dianhydride (BTDA), respectively. The new diamine was synthesized via fluoroalkylation of 4-acetamidophenol with BrCF2CF2Br followed by Zn-mediated elimination and exothermic cyclodimerization. The polymers were characterized by means of FT-IR, inherent viscosity, solubility determination, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). TGA studies indicated that the polymers were all stable up to 480 degrees C. DSC results show that two of the three polymers have a T-g below 150 degrees C. The polymers were found to be soluble in the commonly used polar solvents. Thus the polymers containing perflurocyclobutane rings exhibited excellent solubility and processability.
