A new method for determining the crystallinity fraction of semi-crystalline polymers from X-ray powder diffraction measurements is presented. Using the scattering of an amorphous sample of the same material and a convenient expression for the disorder factor, the method can lead to precise separatio
The sensor and control devices of a d.s.c.-7 Perkin Elmer differential scanning calorimeter have been incorporated into a system for measurement of enthalpies of sublimation. The system was tested with four sublimation reference substances: naphthalene, iodine, benzoic acid and ferrocene between the
