| Abstract: | New polyesterimides containing a bicyclo-octene ring were synthesized by the polycondensation reaction of N,N′-dicarboxymethyl(bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid diimide)dimethylester and N,N′-dicarboxyphenyl(bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid diimide)dimethylester with various aliphatic diols. These polymers thus obtained are soluble in m-cresol, dimethylformamide (DMF), dimethylacetamide (DMAc) and dimethylsulfoxide (DMSO) except those from ethylene glycol. The polymers showed thermal stability above 350°C. |
