Poly(3‐hydroxyalkanoate)‐g‐poly(ethylene glycol) crosslinked graft copolymers are described. Poly(3‐hydroxyalkanoate)s containing double bonds in the side chain (PHA‐DB) were obtained by co‐feeding Pseudomonas oleovorans with a mixture of nonanoic acid and anchovy (hamci) oily acid (in weight ratios of 50/50 and 70/30). PHA‐DB was thermally grafted with a polyazoester synthesized by the reaction of poly(ethylene glycol) with MW of 400 (PEG‐400) and 4,4′‐azobis(4‐cyanopentanoyl chloride). Sol‐gel analysis and spectrometric and thermal characterization of the networks are reported.
