Abstract:V diplomski nalogi je prikazana tiol-en polimerizacija za pripravo poroznih polimerov iz pentaeritritol tetra(3-merkaptopropionata) in polietilen glikol diakrilata ali polietilen glikol dimetakrilata. Željene materiale z odprto porozno strukturo smo poskušali pridobiti s spreminjanjem razmerja med monomerom in oligomerom ali dodajanjem novih monomerov. Vzorce smo po pripravi analizirali z vrstičnim elektronskim mikroskopom, GeoPyck 1365 densiometrom in FT-IR spektrofotometrom. Pripravili smo vzorce, ki imajo na nekaterih delih poliHIPE strukturo na drugih pa nekaj med poliHIPE in bikontinuirno strukturo. Sklepamo, da je do tega prišlo zaradi fazne inverzije.

Title:Cross-Linking of peg polymers with multifunctional thiols by click chemistry
Abstract:Thiol-ene polymerization for the preparation of porous polymers from pentaerythritol tetra(3-mercaptopropionate) and polyethylene glycol diacrylate or polyethylene glycol dimethacrylate is shown in the thesis. We tried to obtain the desired materials with an open porous structure by changing the ratio between the two polymers or adding new polymers to the existing ones. After preparation, the samples were analyzed using a scanning electron microscope, GeoPyck 1365 densiometer and FT-IR spectrophotometer. We prepared samples that have a polyHIPE structure on some parts and something between a polyHIPE and a bicontinuous structure on others. Assumably this is due to a phase inversion.
Keywords:polyHIPE, bicontinuous structure, polymer
