Investigation of the morphology and surface properties of crosslinked poly(urethane-ester-siloxane)s / Ispitivanje morfologije i površinskih svojstava umreženih poli(uretan-estar-siloksana)
(Association of Chemical Engineers of Serbia, 2012)
Two series of crosslinked poly(urethane-ester-siloxane)s were synthesized from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS- -EO), 4,4'-methylenediphenyl diisocyanate and Boltorn® hyperbranched ...
Influence of starch origin on rheological properties of concentrated aqueous solutions / Uticaj porekla skroba na reološka svojstva koncentrovanih rastvora skroba u vodi
(Association of the Chemical Engineers of Serbia, 2011)
The rheological properties of corn and potato starch concentrated aqueous solutions were investigated at 25 °C. The starches were previously dispersed in water and the solutions were obtained by heating of dispersions at ...
Removal of ethylene oxide from waste gases by absorption / Uklanjanje etilen-oksida iz otpadnih gasova postupkom apsorpcije
(Association of Chemical Engineers of Serbia, 2011)
Ethylene oxide (EtO) is an organic compound, which is used as a starting material in the production of polymers and as sterilizing agent for thermolabile materials. Although ethylene oxide is not common as an organic ...

Plant waste materials from restaurants as the adsorbents for dyes / Iskorišćenje sirovog otpada iz restorana za adsorpciju boja
(Association of Chemical Engineers of Serbia, 2015)
This paper has demonstrated the valorization of inexpensive and readily available restaurant waste containing most consumed food and beverage residues as adsorbents for methylene blue dye. Coffee, tea, lettuce and citrus ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
Rheological behaviour of thermoplastic poly(ester-siloxane)s / Reološko ponašanje termoplastičnih poli(estar-siloksana)
(Association of Chemical Engineers of Serbia, 2010)
Two series of thermoplastic elastomers (TPES), based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were analyzed by dynamic mechanical spectroscopy. In the ...
Improvement of cavitation resistance of composite films using functionalized alumina particles
(Savez hemijskih inženjera, Beograd, 2018)
Composite films having the UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina (Al2O3 Fe) based particles were prepared and subjected ...
