Abstract
  • The synthesis and the chemical characterization of some novel random copolyethersulfones of the type P(ESES-co-EES) (Polyethersulfone-ethersulfone:Polyetherethersulfone), is reported. The ESES:EES molar ratio was varied from 80:20 to 20:80 and all the copolymers were terminated with reactive amino groups, and then were fully characterized through (1H and 13C)-NMR and MALDI-TOF MS anal. to confirm their chem. structures and chem. compns. End chains were revealed by these techniques. Contrary to chlorine-ended copolymers, oligomers terminated with hydroxyl groups were revealed in the amine-ended copolymers, indicating that transetherification reactions occur during the capping reaction with m-aminophenol. Cycles were also revealed by MALDI-TOF MS, that revealed also some unexpected end chains may be formed for the impurities in the feed. The glass transition temps. of the copolymers have been detd. by differential scanning calorimetry (DSC). (literal)
