| 中文摘要 | a series of dianhydride monomers, 2,2'-disubstituted-4,4',5,5'-biphenyltetracarboxylic dianhydride (substituents = phenoxy, p-methylphenoxy, p-tert-butylphenoxy, nitro, and methoxy) were synthesized by the nitration of an n-methyl protected 3,3',4,4'-biphenyttetracarboxylic dianhydride (bpda) and subsequent aromatic nucleophilic substitutions with aroxides (naoar) or methoxide. these dianhydrides were polymerized with various aromatic diamines in refluxing m-cresol containing isoquinoline to afford a series of aromatic polyintides. the effects of varying 2,2'-substituents of the dianhydride (bpda) moiety on the properties of polyimides were investigated. it was found that polyimides from the dianhydrides containing phenoxy, p-methylphenoxy, and p-tert-butylphenoxy side groups possessed excellent solubility and film forming capability whereas polyimides from 2,2'-dinitro-bpda and 2,2'-dimethoxy-bpda were less soluble in organic solvent. the soluble polymers formed flexible, tough and transparent films. the films had a tensile strength, elongation at break, and young's modulus in the ranges 102-168 mpa, 8-21%, 2.02-2.38 gpa, respectively. the polymer gas permeability coefficients (p) and ideal selectivities for n-2, o-2, co2 and ch4 were determined for the -oar substituted polyimides. the oxygen permeability coefficient (p-o2) and permselectivity of oxygen to nitrogen (po2/n-2) of the films were in the ranges 3.4-11.3 barrer and 3.8-4.6, respectively. |
