A random ethylene-propylene rubber copolymer with functional ester or anhydride groups and an ethylene vinilacetate copolymer modified by a partial transformation of acetate groups in alcoholic groups were used as minor components to obtain binary poly(D(-)3-hydroxy-butyrate) blends by melt-mixing. The influence of the rubbery impact modifier on the morphology and on the tensile and high-speed fracture behaviour of such blends was investigated. Better properties were found when anhydride groups were present on the rubbery component. This was attributed to chemical interactions occurring between the dispersed phase and the matrix during the blending process.
