Melt Blends of Poly(lactic acid)/Natural Rubber and Liquid Epoxidised Natural Rubber

Although poly(lactic acid) (PLA) is among widely used biodegradable polymers, it has limited applications due to its inherent brittleness, low elongation at break and toughness. Blending with natural rubber (NR) and epoxidised natural rubber (ENR) seems to be a promising alternative, as both materia...
