✦ Synopsis
The electrospray ionization tandem mass spectrometry technique applied for the first time to aliphatic polyester analysis, allowed fast and reliable identification of the various macromolecules of poly(3hydroxybutanoic acid) (PHB), synthesized via ring-opening polymerization of b-butyrolactone. It was demonstrated that the biomimetic polymers studied contain various end groups, depending on the anionic initiator employed, and show close similarity to the natural PHB produced by enzymes in living cells of prokaryotic and eukaryotic organisms.

Electrospray ionization tandem mass spectrometry was applied to study poly(propylene oxide) obtained in the presence of potassium hydride. It was found that the polyether chains possess different starting groups, i.e. those situated at the beginning of the polymer backbone. These were isopropoxy, hy
