Rheomechanical and morphological study of compatibilized PP/EVOH blends

Morphological, thermal, rheological, and mechanical properties of PP/EVOH blends compatibilized with PP‐g‐IA

“…Ares et al reported that the addition of a compatibilizer improves the mechanical properties as well as the shear and extensional flow properties. They found that 10 wt% compatibilizer was optimal for enhancing the mechanical properties .…”

“…Plastic materials have many advantages: they are flexible, lightweight, transparent, inexpensive, easy to manufacture, and recyclable. Food packaging materials are required to have strong barrier properties as well as mechanical strength, besides being inexpensive .…”

“…On the other hand, ethylene vinyl alcohol (EVOH) shows excellent barrier properties toward gases such as oxygen and carbon dioxide (CO 2 ), as well as high resistance to hydrocarbons. However, EVOH is highly sensitive to humidity due to abundant hydroxyl (‐OH) groups in its molecular structure . These hydroxyl groups are responsible for the hydrophilic properties of the material, rendering it poorly resistive to water .…”

“…This technique has the advantage of enhancing both gas and moisture barrier properties. However, this co‐extruded multilayer films present difficult recycling problems because dissimilar resins are bonded together in a composite structure .…”

The influence of epoxy resin on the morphological and rheological properties of PET/PA66 blend

“…Immiscible blends, when subjected to shear, show a higher elasticity presented as a plateau in the modulus curve at low frequency region than the individual precursors due to shape relaxation of droplets (Riemann et al 1997;Bousmina et al 2001;Fahrlander et al 2001;Van Hemelrijck and Van Puyvelde 2005;Mechbal and Bousmina 2007;Yee et al 2007;Silva et al 2007;Ares et al 2009). …”
