After melt blending, the blends were almost
amorphous, and ENR hindered the crystallization of PLA
due to the crosslinking between ENR and PLA molecular chains.
The incorporation of ENR20 greatly reduced the thermal stability
of the PLA, while ENR50 had a less impact. The impact strength
and elongation at break of the blends were enhanced with ENR
content whereas resulted in reduced tensile strength and modulus.
