In this study, the nature of the linear thermal expansion of injection-molded isotactic polypropylene (iPP) was investigated by temperature-variable small-angle X-ray scattering (SAXS) and...

Isotactic polypropylene (iPP) is one of the most impor-tant commercial polymers because of its relatively low cost, versatility, recyclability and good mechan-ical performance in engineering …

Tailoring of Morphology and Mechanical Properties of Isotactic Polypropylene by Processing a 1Leibniz-Institut für Polymerforschung Dresden, 2DESY, Hamburg, Germany

The atactic line is between the iso and syndio lines. As effective as Raman spectroscopy, and much more sensitive to distribution of sequences. 1H NMR spectroscopy is not very sensitive …

Two different samples of isotactic polypropylene films were analyzed in this report to illustrate how polarized Raman spectroscopy can be used to evaluate molecular orientation.

Test liquids not known; from advancing contact angle. Isotactic PP. Test liquids: water and diiodomethane; washed with toluene and isopropanol, then dried overnight. Test liquids: water, …

periodically repeating unit cell cannot be formally defined. This study focuses primarily on isotactic polypropylene (iPP), which occurs in three different bulk polymorphs depending on how the …
