Gel-Type Polyacrylic Resins Cross-Linked with Trimethylolpropanetrimethacrylate: The Issue of Their Nanostructure and Molecular Accessibility Unveiled with a Combination of Inverse Steric Exclusion Chromatography (ISEC), and ESR and CP-MAS 13C NMR Spe...

Original language description

Six gel-type functional resins, that is, three poly-DMAA-co-TMPTP (DMAA=N,N-dimethylacrylamide, TMPTP=trimethylolpropyltrimethacrylate) samples with different degrees of cross-linking (0.6, 1.2, 1.7 % mol) and three poly-DMAA-co-MA-co-TMPTP (MA=methacrylic acid, ca. 5.5 % mol) samples with 1.7, 3.5, and 7 % mol cross-linking were investigated with ISEC (inverse steric exclusion chromatography), and ESR and CP-MAS (cross polarization magic angle spinning) 13C NMR spectroscopy after swelling in water andother solvents. This unprecedented combination of conceptually independent physicochemical techniques provides a thorough overall consistent picture of the morphology of the resins on the nanometer scale and of the molecular accessibility of the swollenpolymer framework to the paramagnetic probe TEMPONE (2,2,6,6-tetramethyl-4-oxo-1-oxypiperidine) and to selected solvents.

Gelové polyakrylátové polymery zesítěné Trimethylolpropantrimetakrylátem: Nanostructura and molekulární dostupnost hodnocená kombinací inverzní sterické exkluzní chromatografie (ISEC), a ESR a CP-MAS 13C NMR spektroskopií

Czech description

6 funkcionálních polymerů gelového typu, z toho 3 různě zesítěné poly-DMAA-co-TMPTP (DMAA=N,N-dimethylakrylamid, TMPTP=trimethylolpropyltrimethakrylát) a 3 poly-DMAA-co-MA-co-TMPTP (MA= kyselina methakfylová) byly po zbobtnání ve vodě a jiných rozpustidlech zkoumány pomocí ISEC (inverzní sterické exkluzní chromatografie), a ESR a CP-MAS 13C NMR spektroskopie. Tato kombinace koncepčně nezávislých fyzikálně-chemických technik poskytla konzistentní představu o morfologii zkoumaných materiálů.
