Popis:	Blends of poly (3-hydroxybutyrate-co-4-hydroxybutyrate) [P (3HB-co-4HB)] with poly(L-lactide) (PLA) were prepared by melt-mixing and subsequent injection molding, and their mechanical properties and morphology were investigated. The results show that the tensile properties, impact strength and spherulitic morphology depend strongly on the composition of the blend. The point of transition shows that phase inversion takes place at composition with 40 weight fraction of PLA in the blend.
