title = "Effect of cooling rate on the crystal polymorphism in beta-nucleated isotactic polypropylene as revealed by a combined WAXS/FSC analysis",
abstract = "The efficiency of γ-quinacridone to nucleate β-crystal formation in isotactic polypropylene (iPP) at rapid cooling has been evaluated by a combination of fast scanning chip calorimetry (FSC) and wide-angle X-ray scattering (WAXS). For samples with different amount of γ-quinacridone, FSC experiments revealed information about a critical cooling rate above which the crystallization temperature decreases to below 105 °C, that is, to temperatures at which the growth rate of α-crystals is higher than that of β-crystals. Microfocus WAXS analysis was then applied to gain information about the competition of formation of β- and α-crystals in samples prepared at defined cooling conditions at rates up to 1000 K/s in the FSC. For iPP containing 1 and 500 ppm γ-quinacridone, the crystallization temperature is lower than 105 °C on cooling faster about 10 and 70 K/s, respectively, which then on further increase of the cooling rate leads to a distinct reduction of the β-crystal fraction.",
