## Abstract Polyamides and polyesters based on neocarboranedicarboxylie dichloride and previously not described have been prepared by low‐temperature polycondensation in solution and characterized. In preparing the polyamides, the following diamines were used: benzidine, hexamethylenediamine, __m__
## Abstract Sebacyl bisketene was generated in solution at −78°C. Copolymerization in solution at 0°C with the secondary diamines, piperazine and __N__,__N__′dimethyl‐1,6‐hexamethylenediamine, yielded the polyamides poly(1,4‐piperazylsebacyl) and poly[(methylimino)hexamethylene(methylimino)sebacyl]
