Summary : Chemical modification is useful to diversify poly(3‐hydroxyalkanoate)s, for medical and industrial applications. In this manner, transesterification reactions of poly(3‐hydroxy butyrate) were carried out under reflux condition of 1,2‐dichlorobenzene in the presence of 1,4‐butane diol, poly(ethylene glycol) bis(2‐aminopropyl ether) with molecular weights of 1000 and 2000, poly(ethylene glycol)methacrylate or glycerol at 180 °C. Addition reactions of bromine and –SH groups of 3‐mercaptopropionic acid to the double bond of poly(3‐hydroxy‐10‐undecenoate) were also carried out. Functionalized poly(3‐hydroxyalkanoate)s were characterized using 1 H NMR, FTIR, GPC and thermal analysis techniques.
