The orientation of the noncrystalline (amorphous) phase in poly (ethylene terephthalate) fibers is analyzed by separating the amorphous scattering in the wideangle x-ray diffraction patterns into isotropic and anisotropic components. Two parameters are used to characterize the amorphous orientation-
A method is described for the elimination of the intense equatorial maximum due to carbon fibre in the wide angle X-ray diffraction pattern from composite material such as APC-2. A specially prepared sample is required in which the fibres are aligned within the range 45-90 Β° to the specimen surface.
Blends of carboxyl functionalized poly(phenylene sulfide) (PPS) and poly-(ethylene terephthalate) (PET) were shown to undergo an ester interchange reaction during melt blending. Pendent carboxyl functionality randomly incorporated along the PPS chain reacts with the ester moiety of PET to form a gra
