  - APPLIED MAGNETIC RESONANCE - Year 2019

  In this paper, the distributions of the 1H nuclear magnetic resonance (NMR) spin–lattice and spin–spin relaxation times are used to characterize the mobility of different sections of macromolecules of aliphatic polyurethanes and the cross-linking density of polymer chains. The NMR relaxometry method with inversion of integral transformation is applied to study the effect of poly (ethylene glycol) and glycerol phosphate calcium...

  - APPLIED MAGNETIC RESONANCE - Year 2020

  In this work, to characterize the mobility of diferent sections of the macromole‑ cules of polyurethane (PUR), polyvinyl alcohol (PVA), and polylactic acid (PLA), as well as the density of crosslinks of the polymer chains when using fllers, we used the distributions of spin–lattice and spin–spin relaxation times for the protons. It is shown that the rigidity of the thermoplastic polymers depends on the sizes of the granules of...

  Analytical data (NMR, MS, FTIR) for nine conjugates of molecular umbrella with cispentacin, Lys(Mca) or Nap-NH2. The conjugates have been rationally designed as potential antifungal agents. 1H NMR and 13C NMR spectra were obtained at 500 MHz Varian Unity Plus spectrometer and the deuterated solvents were used as internal locks. High-resolution mass...

• Nuclear Magnetic Resonance data for the synthesis of esterase cleavable antifungal conjugates containing fatty acids as molecular carriers

  Open Research Data

  open access

  • M. Nowak
  • S. Milewski

  NMR data for novel organic compounds - conjugates composed of C2-18 fatty acid (FA)  residues as a molecular carrier and 5-fluorocytosine (5-FC) as an active agent, released upon the action of intracellular esterases on the ester bond between FA and “trimethyl lock” intramolecular linker.

  - MACROMOLECULES - Year 2012

  Biobased polyamides synthesized from diaminoisoidide (DAII), 1,4-diaminobutane, and sebacic acid are investigated by FT-IR, 13C{1H} magic-angle spinning/cross-polarization (CP/MAS) NMR spectroscopy, and WAXD. Their molecular conformation and mobility undergo distinct changes as a function of temperature and diaminoisoidide content in the compositions. The presence of randomly distributed diaminoisoidide (DAII) in the polyamides...

• Synthesis, structure and properties of novel poly(hydroxyurethane)s obtained by non-isocyanate route

  Publication

  • M. Włoch

  - Year 2016

  Non-isocyanate polyurethanes (NIPUs) can be synthesized by polyaddition of five-membered bis(cyclic carbonate)s and primary diamines. NIPUs are an alternative for the commonly used (in the form of foams, elastomers, coatings or fibers) in the industry polyurethanes obtained using toxic and moisture sensitive diisocyanates, polyols and low-molecular weight chain extenders. The main aim of this work was to synthesize non-isocyanate...
