Spectroscopic studies on the formation of different diastereomers in polyesters based on nadic acid
Nadic acid-based polyesters were prepared by polycondensation with different diols and different stoichiometry of the monomers. Due to the four stereocenters of the acid component, four diastereomers can form in the polyester. The use of different alcohols and influence on the formation of diastereomers in the polyester was investigated. Identification of the stereoisomers has been done with 1D and 2D NMR spectroscopy, which revealed an influence of the diol component on their formation. Further structural elucidation was done by MALDI mass spectrometry and size exclusion chromatography. Another big influence of the diols was found on the glass transition temperatures, which ranged from −30 °C to 40 °C.
期刊介绍：
The scope of the journal is to publish original contributions and reviews on studies, methodologies, instrumentation, and applications involving the analysis and characterization of polymers and polymeric-based materials, including synthetic polymers, blends, composites, fibers, coatings, supramolecular structures, polysaccharides, and biopolymers. The Journal will accept papers and review articles on the following topics and research areas involving fundamental and applied studies of polymer analysis and characterization:
Characterization and analysis of new and existing polymers and polymeric-based materials.
Design and evaluation of analytical instrumentation and physical testing equipment.
Determination of molecular weight, size, conformation, branching, cross-linking, chemical structure, and sequence distribution.
Using separation, spectroscopic, and scattering techniques.
Surface characterization of polymeric materials.
Measurement of solution and bulk properties and behavior of polymers.
Studies involving structure-property-processing relationships, and polymer aging.
Analysis of oligomeric materials.
Analysis of polymer additives and decomposition products.
