Abstract
Poly(3-hydroxyalkanoate)-g-poly(ethylene glycol) crosslinked graft copolyme rs 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 synt hesized by the reaction of poly(ethylene glycol) with MW of 400 (PEG-400) a nd 4,4'-azobis(4-cyanopentanoyl chloride). Sol-gel analysis and spectrometr ic and thermal characterization of the networks are reported.
