| Description
| - The effect of β-nucleation on structure and properties of cast films manufactured from various isotactic polypropylenes has been studied. Two commercial-available polypropylenes - homopolymer (PP) and random copolymer (rPP) - were modified by 0.03 wt.% of specific β-nucleating agent based on N,N´-dicyclohexylnaphthalene-2,6-dicarboxamide. Cast films were prepared from both starting and nucleated polypropylenes using an extrusion line consisting of a Brabender single-screw extruder, slit die and water-cooled chill-rolls. Supermolecular structure of the films was evaluated using wide-angle X-ray scattering; tensile testing was used for the preliminary measurement of mechanical properties. A significant effect of the nucleation and solidification temperature on structure and consequent properties of the films was found in both PP and rPP and is discussed in this work.

- Byl studován vliv β-nukleace na strukturu a vlastnosti litých fólií vyrobených z různých izotaktických polypropylenů. Dva komerčně dostupné polypropyleny - homopolymer (PP) a statistický kopolymer (rPP) - byly modifikovány specifickým β-nukleačním činidlem (N,N'-dicyklohexylnaftalen-2,6-dikarboxamid) v množství 0.03 hm.%. Lité fólie byly připraveny z čistých i nukleovaných polypropylenů pomocí vytlačovací linky skládající se z jednošnekového vytlačovacího stroje Brabender, širokoštěrbinové hlavy a vodou chlazených válců. Nadmolekulární struktura filmů byla sledována pomocí širokoúhlé rentgenografie, tahová zkouša sloužila k základnímu určení mechanických vlastností. Byl pozorován výrazný vliv nukleace a teploty chlazení na strukturu a vlastnosti fólií vyrobených z obou PP i rPP. (cs)
