  • Synteza, budowa i właściwości poliestrouretanów sieciowanych metakrylanem metylu
    Publikacja

    - Rok 2005

    Nową grupę poliestrouretanów (PEU) sieciowanych metakrylanem metylu otrzymano z nienasyconych prepolimerów uretanowych zsyntetyzowanych z oligo(alkilenoestro)dioli (OEA) zawierającą wiązania podwójne. Budowę otrzymanych PEU ustalono na podstawie analizy widm FTIR. Wyniki badań statycznych i dynamicznych właściwości mechanicznych oraz właściwości termicznych wykazały, że uzyskane PEU są interesującą grupą polimerów, których właściwości...

  • Novel, Fully Biobased Semicrystalline Polyamides
    Publikacja

    - MACROMOLECULES - Rok 2011

    Novel, semicrystalline polyamides and co(polyamides) were synthesized from biobased sebacic acid (SA), 2,5-diamino-2,5-dideoxy-1,4;3,6-dianhydroiditol (diaminoisoidide, DAII) as well as from 1,4-diaminobutane (DAB), also known as putrescine in nature. Low molecular weight polyamides were obtained by melt polycondensation of the salts based on these monomers or by interfacial polycondensation. In order to increase their molecular...

    - MACROMOLECULES - Rok 2012

    Novel, semicrystalline polyamides and copolyamides were synthesized from a new carbohydrate-based diamine, namely isoidide-2,5-dimethyleneamine (IIDMA). In combination with 1,6-hexamethylene diamine (1,6-HDA) as well as the biobased sebacic acid (SA) or brassylic acid (BrA), the desired copolyamides were obtained via melt polymerization of the nylon salts followed by a solid-state polycondensation (SSPC) process. Depending on the...

    - MACROMOLECULES - Rok 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...

  • Novel Biomass-Based Polymers: Synthesis, Characterization, and Application
    Publikacja

    - Rok 2012

    A wide range of polymers were prepared from biomass-derivatives, using different polymerization mechanisms. Well-defined, fully hydroxy-functional polyesters based on aliphatic diols were synthesized, using either conventional metal-based catalysts or the organic superbase 1,5,7-triazabicyclododecene (TBD). Unsaturated polyesters were also made, offering additional functionality to these biobased resins. Metal-catalyzed or enzymatic...

    - MACROMOLECULES - Rok 2012

    Isohexides, like e.g. isosorbide, are well-known carbohydrate-based rigid diols which are capable of dramatically increasing the glass transition temperature of polyesters. However, their relatively low reactivity has thus far hampered large-scale industrial applications in the polymer field. Recently, with the aim to increase reactivity while at the same time retain rigidity, we have developed a new isoidide dicarboxylic acid...

  • Structure and Molecular Dynamics in Renewable Polyamides from Dideoxy-Diamino Isohexide
    Publikacja

    - MACROMOLECULES - Rok 2012

    The chemical structure, the conformation, andthe flexibility of the polymer chain fragments present in thepolyamides synthesized from 2,5-diamino-2,5-dideoxy-1,4;3,6-dianhydrosorbitol, 1,4-diaminobutane, and either sebacic orbrassylic acid have been studied by liquid-state 2D NMRspectroscopy viz. correlation spectra (COSY) and heteronuclearmultiple-bond correlation spectra (gHMBC), by 13Ccross-polarization/magic-angle spinning...

    - PROGRESS IN ORGANIC COATINGS - Rok 2014

    Linear and branched bio-based semi-aromatic (co)polyesters were evaluated as resins for solvent-basedand powder coatings. Dimethyl-2,5-furandicarboxylate (DMF), 2,3-butanediol and various multifunc-tional comonomers were used to synthesize amorphous hydroxyl-end-capped (co)polyesters. The resinswere cross-linked using the -caprolactam blocked trimer of isophorone diisocyanate. Both the solvent-based and powder coatings proved to...
