## 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)βpoly(ether biphenyl ether ketone ketone) copolymers were studied by using small angle Xβray scattering and the oneβdimensional electron density correlation function method. The results revealed that structures of the aggregated state of the
## Abstract Thermal expansivities along the a, b, and c axes of the orthorhombic unit cell of poly (etherβetherβketone (PEEK) crystals have been determined from 160 to 470 K by wideβangle xβray diffraction. The expansivities along the a and b axes are positive while the expansivity along the c (cha
