This article presents the results obtained by the ultrasound-assisted synthesis of sucrose and fructooligosaccharides (FOS) esters with fatty acids (palmitic and 10-undecylenic), the identification of the products and the study of their possible application as plasticizers in plastics processing. Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (1H and 13C NMR) spectroscopy were used to identify the synthesized carbohydrate esters. The plasticizing effect of the sucrose palmitate applied in polyvinyl chloride (PVC) was evaluated by the glass transition temperatures; the decrease of the Tg with the increase of the ester content could be accepted as confirmation of the esters' plasticizing effect.

The antimicrobial activity of the synthesized sucrose and FOS esters was evaluated; the results allowed us to conclude that the 10-undecynoyl esters of sucrose and fructooligosaccharides could be successfully applied as potential antimicrobial agents, as well. The sucrose palmitate plasticizing effect was evaluated by determining the glass transition temperatures of thin polyvinyl chloride films on the basis of differential scanning calorimetry (DSC) and changes of mechanical properties. The results showed a decrease of the glass transition temperature with the increase of the ester content, which confirmed the plasticizing effect of the obtained esters.

More about this publication?
  • This journal publishes high quality peer reviewed original research and review articles on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. JRM showcases both fundamental aspects and applications of renewable materials. The fundamental topics include the synthesis and polymerization of biobased monomers and macromonomers, the chemical modification of natural polymers, as well as the characterization, structure-property relationships, processing, recycling, bio and environmental degradation and life cycle analysis of the ensuing materials, in view of their potential applications. Within this sustainability approach, green chemistry processes and studies falling within biorefinery contexts are strongly favored.
