Abstract
U ovom radu pripremljeni su polimerni filmovi mješavina poli(vinil-alkohol)/poli(etilen-oksid) (PVAL/PEO) razliĉitih sastava. Filmovi dobiveni tehnikom lijevanja iz otopine pri datim uvjetima nisu zadovoljavajuće kvalitete. S ciljem utvrĊivanja možebitnih interakcija istraživanih polimera primjenjeni su infracrvena spektroskopija s Fourierovom transformacijom (FT-IR) i diferencijalna pretražna kalorimetrija (DSC). Temeljem rezultata FT-IR analize može se potvrditi postojanje interakcija PVAL-a i PEO-a u mješavinama u vidu vodikove veze. S druge strane, temeljem rezultata DSC analize, odnosno neznatne promjene karakteristiĉnih temperatura toplinskih prijelaza nije mogući potvrditi postojanje interakcija u istraživanim mješavinama.
Abstract (english)
In this paper, polymer films of poly(vinyl alcohol)/poly(ethylene oxide) (PVAL/PEO) blends of different compositions were prepared. Films obtained by the solution casting technique under the given conditions are not of satisfactory quality. In order to determine possible interactions of the investigated polymers, infrared spectroscopy with Fourier transform (FT-IR) and differential scanning calorimetry (DSC) were applied. Based on the results of FT-IR analysis, the existence of interactions of PVAL and PEO in blends in the form of hydrogen bonds can be confirmed. On the other hand, based on the results of DSC analysis, i.e. a slight change in the characteristic temperatures of thermal transitions, it is not possible to confirm the existence of interactions in the investigated blends.
