    Synthesis and use of itaconic esters in emulsion polymerization
    • This thesis explores the synthesis of innovative aqueous dispersions from renewable resources through radical emulsion polymerization, addressing the need to replace limited petrochemical materials. These dispersions have promising applications as binders in paints, coatings, water-based adhesives, cosmetics, pharmaceuticals, and diagnostics. A key starting material is itaconic acid, a biotechnological mass product similar to acrylic and methacrylic acid. Itaconates are synthesized via esterification of itaconic acid or anhydride with suitable fatty alcohols to create monomers for emulsion polymerization. New monomers derived from monosaccharides and itaconic acid are also introduced. Notably, hydrophobic sugar methacrylate is synthesized from 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose in a single step. Sugar latexes are produced through batch emulsion polymerization of sugar methacrylate and fatty alcohol itaconates, alongside other latexes based on sugar methacrylate and commercial fatty alcohol acrylates. The copolymerization behavior of itaconates with sugar methacrylate is examined in both conventional and miniemulsion processes. The study investigates the colloidal, rheological, thermal, optical, and molecular properties of the resulting polymers, analyzing how varying polymerization conditions and the aliphatic structure of fatty alcohol itaconates affect polymerization kinetics and latex characteristics.
