中文摘要	2,2'-bis(3,4-dicarboxyphenoxy)-1,1'-binaphthyl dianhydride was used as a new monomer with various aromatic diamines to obtain polyimides by the usual two-step method. the bis(ether anhydride) was prepared by a nucleophilic substitution of i,1'-bi-2-naphthol with n-phenyl-4-chlorophthalimide, n-methyl-4-nitrophthalimide or 4-nitrophthalonitrile in aprotic polar solvent, and subsequent hydrolysis of the resulting bis(ether imide)s or bis(ether dinitrile), and then dehydration of the corresponding tetracarboxylic acid to afford the dianhydride. most of the obtained polyimides were soluble in chloroform, pyridine, dmf, etc. the polyimide prepared from p-phenylene diamine was partial crystalline, whereas the others showed amorphous patterns in a waxd study. these polymers have glass transition temperatures between 255-294 degrees c and 5% weight loss temperatures in the range of 502-541 degrees c in nitrogen and 473-537 degrees c in air.
