20.500.12556/DKUM-66842 Funkcionalizacija poli(glicidil) metakrilatov z multifunkcionalnimi amini Functionalization of poly(glycidyl) methacrylates with multifunctional amines V okviru diplomske naloge smo pripravili poli(glicidil) metakrilate z različnim molskim deležem zamreževala etilenglikol dimetakrilata. Kot osnovno tehniko za pripravo polimerov smo uporabili termično polimerizacijo kontinuirne faze emulzije z visokim deležom notranje faze (HIP emulzije – High Internal Phase Emulsion). Vzorce smo pred nadaljnjo funkcionalizacijo očistili nečistoč z izopropanolom v Soxhletovi aparaturi in jih nato posušili na zraku. Pripravljeni polimerni vzorci so nam služili kot osnova za nadaljnjo funkcionalizacijo z različnimi multifunkcionalnimi amini. Izbrani amini so bili 1,8-diaminooktan, tris(hidroksimetil)aminometan in tris(2-aminoetil)amin. Za te amine smo se odločili zaradi različne razvejanosti, dolžine verig in vsebnosti amino skupin. Nato smo vzorce analizirali z različnimi analitskimi metodami. Pri elementni analizi smo potrdili, da je potekla uspešna funkcionalizacija preko obeh postopkov, ki smo jih uporabili. Rezultati kažejo, da se je s povečanjem deleža zamreževala nižal odstotek konverzije. Z vrstičnim elektronskim mikroskopom smo preverili morfologijo osnovnih monolitov. S pridobljenih posnetkov je razvidno, da imajo pripravljeni vzorci značilno poliHIPE strukturo in se razlikujejo predvsem v premeru por. Analiza je pokazala, da je vzorec z najvišjim molskim deležem zamreževala imel tudi največji premer por. S porozimetrom smo določili specifično površino osnovnih vzorcev. Rezultati, ki smo jih dobili, so bili okoli 5 m2/g. Na osnovi dobljenih rezultatov lahko sklepamo, da smo s stopnjo zamreženja le malo vplivali na BET specifično površino. Within the scope of this work, poly(glycidyl methacrylate)s with different mole fractions of the cross-linking agent ethylene glycol dimethacrylate were prepared. As a basic technique for the preparation of polymers thermal polymerisation of high internal phase emulsion (HIP emulsion – High Internal Phase Emulsion) was used. Impurities in the samples were cleaned prior to further use for functionalisation with isopropanol by means of a Soxhlet extractor and were then dried at air. The prepared polymer samples were used as the basis for the later functionalisation using various multifunctional amines. The selected amines were 1,8-diaminooctane, tris(hydroxymethyl)aminomethane, and tris(2-aminoethyl)amine. These amines were used due to their different branched shapes, chain lengths, and content of amino groups. The functionalised samples were then analysed using various techniques. With elemental analysis, we conformed that successful functionalization as gone through the two procedures that we have used. Results show that an increase in the share of cross-linking agent cause an increased conversion. SEM analysis was used to check the morphology of the basic monoliths. The images showed that the samples prepared have the typical polyHIPE structure and mainly differ in pore diameter. The analysis showed that the sample with the highest mole fracture of the cross-linking agent also had the largest pore diameter. A porosimeter was used to determine the specific surface area of basic materials. The results obtained were about 5 m2/g. Based on the results, we can conclude that with the crosslinking level, we had little influence on the BET specific surface. funkcionalizacija poliHIPE struktura glicidil metakrilat multifunkcionalni amini termična polimerizacija functionalization polyHIPE structure glycidyl methacrylate multifunctional amines thermal polymerisation true true false [P.
