The thermal stability of poly(sec-butyl methacrylate) / Termička stabilnost poli(sec-butil metakrilata)
(Društvo inženjera plastičara i gumara, Beograd, 2000)
The thermal stability of a series of poly(sec-butyl methacrylate)(PsBMA) samples was investigated by non-isothermal thermogravimetry (TG). The PsBMA samples were synthesised by bulk radical polymerization in the presence ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
The possibilities of applying thermogravimetry in the characterisation of wood types / Mogućnosti primene termogravimetrije u karakterisanju drvnih vrsta
(Faculty of Technology, Novi Sad, 2000)
Thermogravimtery (TG) is a convenient method for the routine, as well as non-standard characterisation of polymeric materials. The changes in wood under various heating conditions were followed and on the basis of the ...
Electrochemical characterization of LiCoO2 / Elektrohemijska karakterizacija LiCoO2
(Faculty of Technology, Novi Sad, 2000)
The electrochemical characteristics of LiCoO2 as a positive electrode for lithium-ion batteries, have been investigated. The LiCoO2 were sintetized from Li2CO3 and Co203 by thermal treatment at 1273 K for 24 h in the air. ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
The thermo-oxidative degradation of poly(2-chloroethyl methacrylate) in the presence of antioxidants / Termooksidativna degradacija poli(2-hloretil metakrilata) u prisustvu antioksidanata
(Association of Chemical Engineers of Serbia, 2000)
The oxidative thermal degradation of poly(2-chloroethyl methacrylate) (PCEMA) was studied in the presence of the following commercial antioxidants: CHIMASSORB 119 (CH 119) and CHIMASSORB 944 (CH 944), both based on amines, ...
Polymer optical fibers today / Polimerna optička vlakna danas
(Association of Chemical Engineers of Serbia, 2000)
Polymer optical fibers (so called POF) are already in wide use in a large number of fields. This paper gives an overview including a background of the development of polymer optical fibers, their advantages, various types ...
The devitrification of PbO-B2O3-ZnO glass doped with Li2O / Rastakljivanje PbO-B2O3-ZnO stakla sa dodatkom Li2O
(Serbian Chemical Society, Belgrade, 2000)
In this paper the effect of the addition of Li2O on the crystallization behavior of PbO-B2O3-ZnO glass was investigated by the differential thermal analysis (DTA) and X-ray powder diffraction (XRPD) methods. The crystallization ...
