Abstract
A study of the phase structure of two linear polyethylene fractions ha s been carried out by Raman spectroscopy and from the analysis of the interface distribution function from the SAXS intensity data. Very goo d agreement is obtained for the core crystallite thickness, the liquid -like region, and the thickness of the interface from these two indepe ndent techniques. Moreover, the X-ray analysis distinguishes isotherma lly formed crystals from quenched crystals in cases where the Raman te chnique is not selective.
