摘要

Aliphatic-aromatic polyimides were synthesized by polycondensation reaction in solvent. The effects of variables such as the kind of solvent, reaction time and temperature, and monomer concentration were investigated in detail on the reaction of 1,2,3,4-butanetetra-carboxylic dianhydride and 4,4'-oxydianiline or 4,4'-diaminodiphenylmethane. The viscosities of polyimides were between 0.22 and 0.46 dL/g. The polyimides were soluble in some aprotic polar solvents, such as N,N'-dimethylacetamide (DMAc), N-methyl-2-pyrrolidone (NMP), dimethylsulfoxide (DMSO), and N,N'-dimethylformamide (DMF). They began to decompose at 380-410 degrees C in air, and 10% weight loss temperatures were 430-450 degrees C. (C) 1996 John Wiley & Sons, Inc. [References: 13]
