## Abstract Thermal expansivities along the a, b, and c axes of the orthorhombic unit cell of poly (etherโetherโketone (PEEK) crystals have been determined from 160 to 470 K by wideโangle xโray diffraction. The expansivities along the a and b axes are positive while the expansivity along the c (cha
## Abstract The crystal structure of poly(aryl ether biphenyl ether ketone ketone) (PEDEKK) was determined to comprise a twoโchain orthorhombic unit cell with dimensions __a__ = 0.778 nm, __b__ = 0.606 nm and __c__ = 2.375 nm by using wideโangle Xโray diffraction (WAXD). According to the orthorhomb
