Abstract
З використанням епоксидної смоли Epidian 5 та етилакрилової кислоти отримано олігомер з кінцевими ненасиченими подвійними зв’язками (ненасичений олігомер, НО). Вивчено вплив природи каталізатора, температури та тривалості процесу на перебіг реакції між смолою та кис-лотою. Запропоновано методику синтезу НО. НО охарактеризовано хімічним та ІЧ-спектроскопічним методами дослідження. НО вивчено в процесах структурування з олігоестеракрилатами ГТМ-3 й МГФ-9 та ненасиченим поліестром ПЕ-246. З метою одержання структурнозабарвлених плівок додатково використані ненасичені азобарвники. Як ініціювальну систему в процесі структурування таких сумішей використано суміш гідропероксиду кумолу та нафтенату кобальту, розчиненого в стирені. З використанням ІЧ-спектроскопії визначено хімізм процесу формування просторовозшитих структур олігоестерних сумішей в присутності НО.
An oligomer with terminal unsaturated double bonds (unsaturated oligomer, UO) has been synthesized from epoxy resin Epidian 5 and ethylacrylic acid. The impact of the catalyst nature, temperature, and reaction duration on the progress of the reaction between the resin and the acid has been studied. A synthetic technique is proposed for producing the UO. The UO has been characterized by chemical and FTIR-spectroscopic analyses. The UO has been examined in the cross-linking processes with oligoesteracrylates TGM 3 and MGP 9 as well as unsaturated polyester PE 246. In order to prepare structurally colored films, unsaturated azo dyes have been additionally used. A mixture of cumene hydroperoxide and cobalt naphthenate dissolved in styrene has been utilized as an initiating system for the cross-linking of the formulations. By using FTIR-spectroscopy, the chemistry of the development of the cross-linked structures of the oligoester mixtures in the presence of the UO has been revealed.
