dc.description.abstractРозроблено новий метод синтезу димекрилату поліетиленгліколю (PEGDM) з різною молекулярною масою (1000, 3000, 6000 і 8000 г/моль) поліетиленгліколю (PEG). Maghnite-H+застосований як еко-каталізатор для заміни токсичного триетиламіну. Maghnite-H+ являє собою протонобмінну монтмориллонітову глину, приготовану за допомогою звичайного обмінного процесу. Синтез проводили з використанням дихлорметану як розчинника в присутності метакрилового ангідриду. Досліджено вплив часу реакції, температури, кількості каталізатора та кількості метакрилового ангідриду для визначення оптимальних умов реакції. Встановлено, що найкращий вихід (98 %) досягається за кімнатної температури протягом 5 год. Структура отриманих макромономерів (PEGDM) підтверджена Фур‘є-спектроскопією, 1H ЯМР і 13C ЯМР методами. За допомогою термогравіметричного аналізу визначено термічну стабільність отриманих макромономерів. Наявність ненасиченої кінцевої групи підтверджено УФ-спектроскопією.
dc.description.abstractA new method to synthesise polyethylene glycol dimethacrylate (PEGDM) with various molecular weights (1000, 3000, 6000 and 8000 g/mol) of polyethylene glycol (PEG) has been developed. This technique consists in using Maghnite-H+as eco-catalyst to replace еriethylamine, which is toxic. Maghnite-H+is a proton exchanged montmorillonite clay which is prepared through a simple exchange process. Synthesis experiments are performed in solution using dichloromethane as solvent in the presence of methacrylic anhydride. The effect of reaction time, temperature, amount of catalyst and amount of methacrylic anhydride is studied in order to find the optimal reaction conditions. The synthesis in solution leads to the best yield (98 %) at room temperature for the reaction time of 5 h. The structure of the obtained macromonomers (PEGDM) is confirmed by FTIR, 1H NMR and 13C NMR, where the methacrylate end groups are clearly visible. Thermogravimetric analysis (TGA) is used to study the thermal stability of these obtained macromonomers. The presence of unsaturated end group was confirmed by UV-Visible analysis.
