Preparation of poly(ethylene glycol) grafted poly(3‐hydroxyalkanoate) networks

Preparation of poly(ethylene glycol) grafted poly(3‐hydroxyalkanoate) networks 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Macromolecular Chemistry and Physics Wiley

Abstract

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.
