Název v původním jazyce

The role of various modifiers in the compatibilisation of PP/PET blends - rheological and structural properties

Popis výsledku v původním jazyce

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 atboth 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 proc
