▎ 摘　　要

Poly(amide-hydrazide)s copolymers were prepared using hydrazide derivative of phenylene diamine to react with aromatic diacid chloride. The wholly aromatic poly(amide-hydrazide)s have better solubility in organic polar solvents, such as N,N-dimethylacetamide, dimethylsulfoxide, 1-methyl-2-pyrollidone, and N,N-dimethylformamide, at room temperature, while still maintaining their high thermal stability. Graphene in the nano size was used as a filler to enhance their thermal and mechanical properties. The polymers as well as the composite were characterized by spectral and mechanical tools as well as by X-ray analysis. (C) 2015 Society of Plastics Engineers
