Description
| - The work focuses on microfibrillar formation in polymer blends during extrusion through a die with semihyperbolic-converging channel. For these purposes, three polyethylene/polypropylene blends with mixing ratios (wt./wt.) 80/20, 70/30 and 60/40 were prepared. Final structure and properties of extruded blends were examined using wide-angle X-ray scattering and tensile testing. It is demostrated that the formation of microfibrillar-phase morphology is achieved in all blends. Structure and properties of these microfibrillar-phase composites are strongly influenced by mixing parameters.

- Práce se zaměřuje na vznik mikrofibrilární struktury v polymerních směsích během vytlačování přes vytlačovací hlavu se semihyperbolickou sbíhavou štěrbinou. Pro tyto účely byly připraveny tři směsi polyetylenu a polypropylenu s poměrem (hm./hm.) 80/20, 70/30 a 60/40. Konečná struktura a vlastnosti vytlačovaných směsí byly studovány pomocí širokoúhlé rentgenografie a tahových zkoušek. Bylo potvrzeno, že mikrofibrilární struktura vznikla ve všech směsích. Struktura a vlastnosti těchto mikrofibrilárních kompozitů jsou silně závislé na poměru složek. (cs)
