Abstract
We carried out testing of film-formation and antimicrobial properties of polymer/aromatic alcohol (AA) compositions. The compositions consisted of AA (phenol, resorcin, pyrocatechol, p-methoxyphenol or 4-hydroxybenzoic acid) with polar hydrophilic polyvinyl butyral (PVB) or nonpolar hydrophobic ethylene propylene rubber (SKEP). The polymers and AAs were tested for solubility in various solvents in order to choose those that would be suitable for preparation of simultaneous polymer/AA solutions and ensuing films. Differential scanning calorimetry and IR spectroscopy were used to determine morphology and structure of SKEP/AA and PVB/AA compositions. Since SKEP does not blend with AAs, these compositions are two-phase systems. In contrast, PVB/AA compositions represent monophase systems. PVB compatibility with AAs is explained by establishment of hydrogen bonds. Both types of composition exhibit film-forming properties. SKEP/AA films are characterized by low rigidity, whereas PVB/AA films demonstrate high rigidity. Both types of composition inhibit growth of mold fungi.
