Strain-induced nucleation for establishing highly oriented iPP — •Konrad Schneider — Leibniz-Institut für Polymerforschung Dresden, Germany

The mechanical properties of semi-crystalline materials are mainly determined by the morphology of the material, especially the crystalline phase. This can be controlled in a wide range by nucleating agents. By stretching of partially crystallized material the crystallite orientation of the subsequent crystallized phase can be influenced in a wide range. By simultaneous WAXS (wide angle x-ray scattering) during drawing and crystallization the built-up of the final structures can be followed. It will be shown, how which structural variability is possible by this procedure.
