## Abstract A new monomer, __N,N′‐__bis(4‐phenoxybenzoyl)‐__m__‐phenylenediamine (BPPD), was prepared by condensation of __m__‐phenylenediamine with 4‐phenoxybenzoyl chloride in __N,N__‐dimethylacetamide (DMAc). A series of novel poly(ether amide ether ketone) (PEAEK)/poly(ether ketone ketone) (PEK
## Abstract Thermal properties of poly(ether ether ketone ketone) (PEEKK)/poly(ether biphenyl ether ketone ketone) (PEDEKK) copolymers were investigated by means of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The glass transition temperature (__T__~g~) increases fr
## Abstract Structures of poly(ether ether ketone ketone)‐poly(ether biphenyl ether ketone ketone) copolymers were studied by using small angle X‐ray scattering and the one‐dimensional electron density correlation function method. The results revealed that structures of the aggregated state of the
