| Abstract: | Bifunctional arylcyanoacetic esters were oxidatively coupled to high molecular weight, colorless, amorphous polymers, soluble in common organic solvents. Brittle films were obtained by casting or compression molding. Thermal stability of the polymers is poor due to the weak C? C bond formed by oxidative coupling. Radical dissociation-recombination of this bond (evidenced by ESR) results in meso-dl equilibration, lowering the Tg of the polymers. |
