The maximum tensile strength and thermal stability of theNR-g-CSt/MENR blend was found when using a 50:100 NR-g-CSt/MENR blend. The interaction between the NR-g-CSt and theMENR was also improved which was confirmed by AFM and SEM.The films incorporating lower concentrations of MENR (e.g., the50:100 MENR/NR-g-CSt blend) demonstrated good biodegradationin soil. The resulting polymer blend has possible applications inpackaging and agriculture.
