## Abstract Sebacyl bisketene was generated in solution at โ78ยฐC. Copolymerization in solution at 0ยฐC with the secondary diamines, piperazine and __N__,__N__โฒdimethylโ1,6โhexamethylenediamine, yielded the polyamides poly(1,4โpiperazylsebacyl) and poly[(methylimino)hexamethylene(methylimino)sebacyl]
## Abstract This paper deals with the synthesis of polyamides based on the natural diamine, Lโlysine, on the one hand, and diacids, adipic or glutaric, on the other hand. They were obtained by polycondensation of active diesters, pentachlorophenyl and pentafluorophenyl esters. LโLysine being nonโsy
