N2 - Fully bio-¿based and biocompostable poly (lactic acid)¿/poly (ß-¿hydroxybutyrate-¿co-¿ß-¿hydroxyvalerate) (PLA¿/PHBV) blends were prepd. by melt compounding. PHBV with a high ß-¿hydroxyvalerate content (40 mol¿%) was used in this work. Miscibility between the PLA and the PHBV, phase morphol., thermal behavior, mech. properties and toughening mechanism of the PLA¿/PHBV blends were investigated. The blends showed two sep. glass transition temps., indicating that the PLA and PHBV are not miscible. Transmission electron microscopy (TEM) showed that PHBV changed gradually from a dispersed phase into a continuous matrix up to 50 wt¿% of the PHBV. At low PHBV content (
