Copolymers of poly(3‐hydroxyoctanoates) (PHAs) containing repeating units with unsaturated or brominated pendant side chains have been obtained from cultures of Pseudomonas oleovorans grown on mixtures of octanoic acid and undecenoic acid or 11‐bromoundecanoic acid as carbon sources. These polymers, bearing reactive functionalities, have been used to graft acetylated maltosyl units either by anti‐Markovnikov addition to the double bond or S N 2 substitution of the halogen. De‐ O ‐acetylation of the sugar moieties yielded PHAs with new properties.
