Abstract

U ovom radu sintetizirani su kopolimeri N-vinil-2-pirolidona (VP) i poli(etilenglikol)metiletermetakrilata (M-PEG) te su analizirana njihova svojstva. Sintetiziran je kopolimer poli(N-vinil-2-pirolidon-ko-etilenglikolmetileter-metakrilat) (VP-ko-M-PEG) s različitim molarnim udjelima monomera u reakcijskoj smjesi: V80/M20, V60/M40 V50/M50, V20/M80 gdje V označava Nvinil-2-pirolidon, a M označava
poli(etilenglikol)metileter-metakrilat. Ukupne početne koncentracije monomera u reakcijskim smjesama su 1 mol/dm^3. Kao inicijator korišten je Trigonox 21s. Za svaki udio provedene su dvije sinteze, do niskih konverzija u trajanju od 3h te do visokih konverzija u trajanju od 24h. Priređeni kopolimeri karakterizirani su FTIR spektroskopijom kako bi se odredio njihov kvalitativni sastav, dok su im toplinska svojstva analizirana diferencijalnom pretražnom kalorimetrijom (DSC).

Abstract (english)

In this work, copolymers of N-vinyil-2-pyrrolidone and ethylene glycol methacrylate were synthesized and their properties were analyzed. Poly(N-vinyl-2-pyrrolidone-co- ethylene glycol methacrylate) copolymers (VP-co-M-PEG) was synthesized with different molar ratios of monomers in the reaction mixture: V50/M50, V80/M20, V60/M40, V20/M80 where V stands for N-vinyl-2-pyrrolidone and M stands for ethylene glycol methacrylate. Total monomer concentration was 1 mol/dm^3. Trigonox 21s was used as an initiator. Two syntheses were performed for each ratio, one for low conversions that lasted 3 hours and one for high conversions that lasted for 24 hours. Composition of synthesized copolymers was characterized by FTIR spectroscopy and heat properties were analized by differential scanning calorimetry (DSC).
