Molecular level structure of novel synthetic analogues of aliphatic biopolyesters as revealed by multistage mass spectrometry

Molecular architecture of novel potentially bioactive (co)oligoesters containing pesticide moieties established by electrospray ionization multistage mass spectrometry

“…[11,12,[24][25][26][27] Also, in research on the molecular structures of polyhydroxyalkanoates and their synthetic analogues, ESI-MS was successfully applied to characterize microbial and synthetic aliphatic (co)polyesters. [28][29][30][31][32] Therefore, in order to obtain more detailed structural information about the obtained potentially bioactive (co)oligoesters, electrospray mass spectrometry was used for their structural studies.…”

Bioactive oligomers from natural polyhydroxyalkanoates and their synthetic analogues

“…The specific synthetic method based on the carbonylation of the respective epoxides under CO at ambient pres- or sure opens up new opportunities for exploring the utility of β-lactones (and in particular precursors of synthetic analogues of natural PHA, i.e., β-substituted β-lactones) as monomers for the synthesis of new polymers with desired properties. Thus, block and random synthetic PHA copolymers were prepared by anionic ROP [41][42][43].…”

Biocompatible terpolyesters containing polyhydroxyalkanoate and sebacic acid structural segments – synthesis and characterization

“…Development of so ionization techniques in mass spectrometry facilitates solving the difficult questions regarding the molecular structure of copolymers. 14,[29][30][31][32][33] To obtain precise information on the structure of the resulting PHBHx oligodiols at the molecular level, electrospray mass spectrometry ESI-MS was used. This technique is very useful for the structural characterisation of partially degraded PHA biopolyesters, especially for characterization of the chemical structure of the end groups of analysed oligomers.…”
