Preparation of methacrylated hydroxybutyrates monomers and polymers
 Liška, Marek ; Mgr. Petra Zbořilová, Ph.D (referee) ; Figalla, Silvestr (advisor)
The aim of this work is the study, design, and preparation of methacrylated derivatives of poly(3-hydroxybutyrate) and the subsequent preparation of polymers from the prepared precursors. A total of six compounds were prepared. The prepared compounds include methyl-3-hydroxybutyrate and ethyl-3-hydroxybutyrate prepared by alcoholytic depolymerization with monofunctional alcohol and their methacrylated derivatives. The preparation of ethylene glycol terminated oligomer of 3-hydroxybutyrate prepared via depolymerization using ethylene glycol in two ways is also an essential part of the work. The first way involves depolymerization using conventional heating and the second one explores the preparation of a series of oligomers with different molecular weights using microwave heating. Methacrylated derivatives of the prepared oligomers were also prepared. The prepared compounds and their actual preparation are characterized using multiple analytical methods including VPO, NMR, GPC, FT-IR, LC-MS, and DSC. A series of polymers were obtained from the prepared compounds by radical polymerization using purple light (with wavelength 405 nm) as the energy source. The prepared polymer networks were characterized by DSC and their tensile strengths were tested.
