Structural Studies of Natural and Bio-Inspired Polyesters by Multistage Mass Spectrometry

  • Marek Kowalczuk

Hyphenation of electrospray ionization with ion-trap multistage mass spectrometry (ESI-MSn) provides characterisation of subtle molecular structure of both synthetic and natural aliphatic polyesters as well as oligomeric products of their biodegradation. Implementation of multistage MS technique for structural studies of the novel bio-inspired polymers including poly[(R,S)-3-hydroxybutyrateJ, a-PHB, telechelics and a-PHB conjugates with oligopeptides has been demonstrated. The novel results concerned with evaluation of the subtle structure of macroinitiators obtained by partial depolymerisation of selected natural poly(3-hydroxyalkanoate)s, PHA, are also presented.
