Morphology, thermal, and mechanical behavior of ethylene octene copolymer toughened polyamide 6/polypropylene nanocomposites

Polyamide 6/polypropylene (PA6/PP = 70/30 parts) blends containing 10 wt% of ethylene octene copolymer (POE) and different loading (2-6 wt%) of organophilic modified monmorillonite (MMT, organocaly) are prepared using a twin screw extruder followed by injection molding. Polypropylene grafted maleic...
