In the foregoing blends, additional compatibilization was needed to obtain promising mechanical properties. It would thus be of interest to use a commercially cost-effective
impact modifier which is compatible with PLA. Afrifah and Matuana [22] blended PLA with a commercial impact modifier (Biomax Strong 100, DuPont), which is a petroleum-based ethylene-acrylate copolymer (EAC). The toughness of the PLA was improved to a certain extent, e.g. by a factor of 4–6 after incorporation of 30 wt.% EAC.
