- W2048699567 abstract "The oxidative thermal degradation of poloxamer 407, a poly(ethylene oxide–propylene oxide–ethylene oxide) triblock copolymer, at 50 and 80 °C in air was studied by solid phase microextraction/gas chromatography–mass spectrometry (SPME/GC–MS). At 80 °C, we found that degradation was initiated on the PPO block of the copolymer by three mechanisms involving hydroperoxyl formation and depropagation. 1,2-propanediol,1-acetate; 1,2-propanediol,2-formate; 1,2-propanediol,1-acetate,2-formate and 2-propanone,1-hydroxy were the first degradation products produced. Random chain scissions and a sharp decrease in the molecular weight of the material followed the initiation period. Formic acid and acetic acid, formed upon degradation, participated in esterification reactions leading to the formation of the formate and acetate forms of 1,2-propanediol and ethanediol. Though degradation at 50 °C was much slower, the oxidative mechanisms leading to low molecular weight formates and acetates were the same as those observed at 80 °C." @default.
