Synthesis and properties of polyesterimides containing a bicyclo‐octene ring
1978
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.
Es wurden neue Polyesterimide, die einen Bicyclooctenring enthalten, durch Polykondensation von N,N′-Dicarboxymethyl-(bicyclo[2.2.2]oct-7-en-2,3,5,6-tetracarbonsaurediimid)-dimethylester und N,N′-Dicarboxyphenyl-(bicyclo[2.2.2]oct-7-en-2,3,5,6-tetracarbonsaurediimid)-dimethylester mit verschiedenen aliphatischen Diolen hergestellt. So dargestellte Polymere sind in m-Kresol, Dimethylformamid, Dimethylacetamid und Dimethylsulfoxid loslich, mit Ausnahme der mit athylenglycol dargestellten. Die Polymeren waren bis oberhalb 350°C thermisch stabil.
