Description
  • Byl studován vliv β-nukleace na strukturu a vlastnosti fólie připravené z izotaktického polypropylenu. Dva komerčně dostupné polypropyleny, homopolymer a statistický kopolymer, byly modifikovány přídavkem 0,03 hm.% specifického β-nukleačního činidla NJ Star NU 100. Fólie byly vytlačeny z obou čistých i nukleovaných polypropylenů pomocí ploché hlavy a vodou chlazených válců. Nadmolekulární struktura fólií byla studována pomocí širokoúhlé rentgenografie. Tahové zkoušky byly použity pro předběžné stanovení mechanických vlastností. Byl pozorován významný vliv nukleace a teploty tuhnutí na strukturu a vlastnosti fólií. (cs)
  • The effect of β-nucleation on structure and properties of cast films manufactured from isotactic polypropylenes has been studied. Two commercial-available polypropylenes - homopolymer and random copolymer - were modified by 0.03 wt.% of specific β-nucleating agent NJ Star NU 100. Cast films were extruded from both starting and nucleated polypropylenes using a slit die and water-cooled chill roll. 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 properties of the films was found.
