A study of polymer crystallization and melting and the effect on morphology and molecular motion

Three polymers, poly(ethylene), poly(trimethylene oxide) and poly(tetramethylene oxide) have been used in a study of the crystallization and melting behaviour of semi-crystalline polymers, and their effect on morphology and molecular motion. Crystallization and morphological phenomena have been examined in detail for poly(trimethylene oxide), using a variety of techniques including wide and small angle X-ray diffraction, dilatometry, optical microscopy, differential scanning calorimetry and by dielectric constant studies.
