| Description
| - Práce se věnuje studiu strukturních a tokových vlastností systémů tvořených polypropylenem (PP) a polyetylentereftalátem (PET), které byly kompatibilizovány malein anhydridem a dále modifikovány přísadami elastomerní povahy. Měření tokových vlastností bylo provedeno na rotačním reometru jak v ustáleném, tak oscilačním režimu. Pro stanovení reologických charakteristik byly též zvoleny dva teplotní režimy, tj. 245°C a 265°C, kdy v prvním případě se jedná spíše o analogii plněných systémů, neboť složka PET není za této teploty roztavena a chová se jako plnivo. Přídavek elastomerů byl cílen ke zlepšení zpracovatelnosti PP/PET směsí a jejich rázových charakteristik. (cs)
- The present paper deals with structural and flow properties of PP and PET blends compatibilised by maleic anhydride (MA) in combination with two modifiers - epoxidized thermoplastic elastomer and silicone/acrylic-based rubber. Rheological experiments at both steady and dynamic shear regimes were performed on rotational cone-plate rheometer at 265°C (above melting temperature of PET) and 245°C (below it). In the latter case, PET particles are not completely melted, acting as soft filler. Increased rheological functions are generally observed for PP/PET/MA (due to enhanced interfacial interactions), which is further increased by elastomeric modifiers. These also bring satisfactory phase structure resulting from possible reactions between functional groups in the modifier and blend components, particularly for epoxy-modified thermoplastic elastomer. The addition of elastomeric modifiers also leads to a significant increase in viscosity of PP/PET blends, which can be utilised in their processing.
