Název v původním jazyce

Impact Strength of Beta-Nucleated Polypropylene

Popis výsledku v původním jazyce

Structural transformations of semicrystalline polymers form an important field of current scientific research. The preparation of controlled supermolecular structure may lead to significant improvements in mechanical, thermal and optical properties. Namely, isotactic polypropylene (iPP) and its properties essentially depend on its crystalline phase composition, which is due to polymorphism of iPP. Thus, the aim of this work is to analyze the influence of the beta-phase content in polypropylene and of its spatial arrangement on mechanical properties, in particular on its impact strength. Commercially available iPP was modified by various amounts of a specific beta-nucleating agent. From the prepared mixtures standard impact testing bars were injection molded using the Demag NC4 injection molding machine. The structure of the specimens was studied by X-ray diffractometry, and impact properties were determined using Ceast Resil 5.5 Charpy impact tester.
