Rheological behavior of polyamide-6/linear low density polyethylene grafted maleic anhydride/monmorillonite nanocomposites and statistical model

Polyamide 6 (PA6) with different linear low density polyethylene grafted maleic anhydride (LDPE-g-MAH) and montmorillonite (MMT) loadings were produced by melt compounding using single screw extruder. In this study a mixture design of experiment covered three ingredients which contribute to the rheo...
