Preparation and characterization of polypropylene/clay nanocomposites
Polypropylene/clay nanocomposites were synthesized by melt compounding with Cloisite® 20A nanoclay and three different types of compatibilizer in a twin-screw extruder. Different loading of polypropylene maleic alternated polymer (X-10016), polypropylene maleic terminated polymer (X-10088) and polyp...
