The influence of antioxidant and post-synthetic treatment on the properties of biodegradable poly(butylene succinate)s modified with poly(propylene oxide) / Uticaj antioksiodansa i načina izdvajanja polimera na svojstva biodegradabilnih poli(butilen sukcinata) modifikovanih poli(propilenoksidom)
(Serbian Chemical Society, Belgrade, 2007)
Novel poly(ester-ether)s based on poly(butylene succinate) (PBS) as the hard segments and 30 mass % of poly(propylene oxide) (PPO) as the soft segments were synthesized with varying amount of the antioxidant (N,N'-diphen ...
Synthesis, structure and properties of thermoplastic poly(ester-siloxane) elastomers
(Serbian Chemical Society, 2006)
Two series of thermoplastic poly(ester-siloxane) elastomers (TPES), with hard segments based on poly(butylene terephthalate) (PBT) and soft segments based on poly(dimethylsiloxane) (PDMS), were synthesized by high-temperature, ...
Heat of vaporization from the corresponding states principle / Određivanje toplote isparavanja na bazi principa korespondentnih stanja
(Association of the Chemical Engineers of Serbia, 2005)
The heat of vaporization was estimated from the corresponding states principle. The reported values of the functions δS(0) and δS(1), or their analytical expressions, are presented. Tabulated values of δS(0) and δS(1) were ...
Stabilization of alpha-glucosidase in organic solvents by immobilization on macroporous poly(GMA-co-EGDMA) with different surface characteristics / Stabilizacija α-glukozidaze u organskim rastvaračima imobilizacijom na makroporoznim (poli) glicidil metakrilatima različitih površinskih karakteristika
(Serbian Chemical Soc, Belgrade, 2006)
alpha-Glucosidase from baker's yeast was immobilized on macroporous copolymers of ethylene glycol dimethacrylate and glycidyl methacrylate, poly(GMA-co-EGDMA), with various surface characteristics and pore sizes ranging ...
Comparative study of cu(2+) adsorption on a zeolite, a clay and a diatomite from Serbia
(Applied Clay Science, 2009)
The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of ...
Aging of the over-voltage protection elements caused by over-voltages
(Microelectronics Reliability, 2002)
The aim of this work is examining the influence of the number of the activation-over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage ...
Determination of tension strength in the longitudinal and circumferentional direction in glass-polyester composite pipes / Određivanje zatezne čvrstoće u uzdužnom i obimnom pravcu u staklo-poliester kompozitnim cevima
(Faculty of Technology, Novi Sad, 2009)
Polymer composite pipes with glass fiber reinforcement have today a wide usage in the chemical and process industries. The basic subject of this paper is the determination and distribution of stresses and strains in ...
Synthesis and characterization of poly(ester ether siloxane)s
(John Wiley and Sons Ltd, 2006)
A series of novel thermoplastic elastomers based on ABA-type triblock prepolymers, poly[(propylene oxide)-(dimethylsiloxane)-(propylene oxide)] (PPO-PDMS-PPO), as the soft segments, and poly(butylene terephthalate) (PBT), ...
