Melt compounding of polypropylene‐based clay nanocomposites

Abstract: Melt compounding of polypropylene-based clay nanocompositesPolypropylene (PP)-based nanocomposites containing 4 wt% maleic anhydride grafted PP (PP-g-MA) and 2 wt% Cloisite 20A (C20A) were prepared using various processing devices, viz., twin-screw extruder (TSE), single-screw extruder (SSE), and SSE with an extensional flow mixer (EFM). Two processing methods were employed: (I) masterbatch (MB) preparation in a TSE (with 10 wt% C20A and clay/compatibilizer ratio of 1:2), followed by dilution in TSE, SSE, or S… Show more

“…The nanofiller was organically modified MMT, C20A, shown in Figure 1. Profiting from years of experience, the master batch method of compounding was selected [32]. Thus, PP with 20 wt% PP-MA compatibilizer was dry blended and fed from a hopper with antioxidant (Irganox B-225 from Ciba), while 10 wt% of organoclay was supplied from a side feeder.…”
