Abstract
U ovom radu sintetiziran je poli(vinil-acetat) (PVAC) emulzijskom polimerizacijom vinil-acetata napravljena je karakterizacija sintetiziranog i izvornog (kupljenog) PVAC-a pomoću infracrvene spektroskopije s Fourierovom tranformacijom (FT-IR) koja je primijenjena za potvrdu strukture polimera, odnosno uspješnosti sinteze PVAC-a emulzijskom polimerizacijom vinil-acetata, zatim diferencijalnom pretraţnom kalorimetrijom (DSC) koja je dala uvid u toplinska svojstva PVAC-a i termogravimetrijskom analizom (TG) koja je dala uvid u toplinsku razgradnju PVAC-a. Usporedbom FT-IR spektrograma izvornog i sintetiziranog PVAC-a dobiven je koeficijent korelacije 87,7% te vrijednost nije dovoljno velika da bi potvrdila da se zaista radi o PVAC-u, meĊutim karakteristiĉne vibracijske vrpce za ĉisti PVAC s blagim odstupanjem ĉime se dokazuje da je PVAC uspješno sintetiziran. DSC normaliziranim krivuljama potvrĊuju se zakljuĉci dobiveni FT-IR-om, ali temeljem vrijednosti staklišta. Preklapanjem DTG krivulja dolazi se do istog zakljuĉka, bliski rezultati u razgradnim stupnjevima potvrĊuju da je sinteza PVAC-a emulzijskom polimerizacijom vinil-acetata uspješno provedena.
Abstract (english)
In this thesis, poly(vinyl acetate) (PVAC) was synthesized by emulsion polymerization of vinyl- acetate and the characterization of synthesized and original (purchased) PVAC was performed using infrared spectroscopy with Fourier transform (FT-IR) which was used to confirm the structure of the polymer, i.e. the success of the synthesis of PVAC by emulsion polymerization of vinyl-acetate, followed by differential scaning calorimetry (DSC) which gave insight into the thermal properties of PVAC and thermogravimetric analysis (TG) which gave insight into the thermal decomposition of PVAC. Comparing the FT-IR spectrograms of the original and synthesized PVAC, a correlation coefficient of 87.7% was obtained and this value is not big enough to confirm that it is indeed PVAC, but it showed characteristic vibration bands for pure PVAC with a slight deviation, which proves that PVAC has been successfully synthesized. DSC normalized curves confirm the conclusions obtained by FT-IR, but based on values of glass transition. By overlapping the DTG curves, the same conclusion is reached, close results in the decomposition steps confirmed that the synthesis of PVAC by emulsion polymerization of vinyl acetate has been successfully carried out.
