  • Unsaturated, biobased polyesters and their cross-linking via radical copolymerization

    Biobased, unsaturated polyesters derived from isosorbide, maleic anhydride and succinic acid were synthesized and characterized. The presence of maleic anhydride units in the structure of the polyesters allowed converting them into cured coatings by radical copolymerization with cross-linking agents such as 2-hydroxyethyl methacrylate, N-vinyl-2-pyrrolidinone, acrylic acid or methacrylamide. The investigated polyesters were obtained...

  • Novel, Fully Biobased Semicrystalline Polyamides

    Publication

    - MACROMOLECULES - Year 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...

  • Impedance evaluation of coatings from biobased material

    Publication

    The authors propose a modification of sodium caseinate edible coating for foodstuff protection. The aim was to improve the film’s barrier properties. It was achieved by the addition of propolis, which is a natural, environmentally friendly product known from its intrinsic sealing action. In the next step, propolis-admixed sodium caseinate films were exposed to elevated temperature for 10 min. This approach was meant to improve...

  • Biobased Ultralow-Density Polyurethane Foams with Enhanced Recyclability

    Publication

    - ACS Sustainable Chemistry & Engineering - Year 2024

    Polyurethane (PUR) foams are widely used in many engineering applications, but their efficient recycling has remained a major challenge for many years. This study presents a novel strategy of incorporating hydrolyzable ester units into the PUR structure to enhance PUR foam recyclability. The present ecodesign concept of PUR materials enables fully the replacement of petrochemical polyols with biobased alternatives and production...

  • Polyester-urethanes modified with gelatine for tissue scaffolds

    Publication

    Novel aliphatic PU foams, modified with gelatine, were obtained in a one-step polymerization process. Hard segments were obtained from 1,6-hexamethylene diisocyanate (HDI) and chain extenders 1,4-butanediol (BDO) or 2-(2-(2-hydroxyethoxy)ethoxy)ethanol (TG), soft segments were obtained from poly(ethylene-buthylene adipate) (EBO) polyol. We examined the PU foams for their sorption capability in canola oil, saline (0.9% NaCl water...
