Biosource materials for coatings

abstrakt

angličtina

The work is focused on the chemical processes leading to the production of polymerizable material precursors made out of the natural sources with the potential for the coatings applications. There are various biosource substrates which can be transformed into the potential coating materials such as vegetable oils, sorbitol or lactic acid. The modification of these reactants via acrylic acid, methacrylic acid and methacrylic anhydride has been studied. Modified vegetable oil structure contains a significant amount of biosource carbon. Sorbitol material precursor derivatives show high glass transition temperature numbers (Tg > 100 °C) after their polymerization and ethyl lactate methacrylate as a polymerizable derivative of lactic acid reached the highest conversion level of 99.9 %. There is a possibility that the fatty acids together with sorbitol derivatives such as isosorbide in the form of an ester can combine their properties. These materials are supposed to be an alternative to the materials used currently for the coating applications like pure acrylates or artificial polyurethanes
