dc.description.abstractOvaj rad je imao za cilj , razvoj postupka sinteze polimernih prekursora mreža na bazi obnovljivih sirovina. Razvijen je postupak sinteze poli laktida u rastvoru dihlor metana. Vreme trajanja postupka sinteze je 6 h, a uspešnost samog procesa je potvrđena metodama identifikacije i karakterizacije dobijenih polimera PLLA. U ovom radu, za ispitivanja dobijenih polimernih materijala, uzimajući u obzir ideju o krajnjoj nameni, korišćene su sledeće metode: GPC ( Gel Permeation Chromarography) za određivanje raspodele molekulske mase; IR spektrofotometrija, prikazuje vibraciju atomskih, molekulskih ili funkcionaknih grupa; i termička analiza TGA i DSC, za praćenje promena pri kontrolisanom zagrevanju i hlađenju. Jedan od ciljeva rada je bio i da se da pregled postojećih teorija ojačanja elastomera punilima sa nano česticama, i ispita ponašanje nano-kompozitnih materiajala pod dejstvom visoko energetskog zračenja ( gama zračenja). U eksperimentalnom delu ispitivani su elastomerni materijale na bazi butadienakrilonitrilnog kaučuka (NBR) i hlorsulfonovanog polietilenskog kaučuka (CSM) . Mešanjem CSM i NBR formiraju se umreženi sistemi, koji se koriste kao prekursori mreža za dobijanje nano-kompozitnih materijala ojačanaih česticama aktivnih punilačađi i silicijum (IV) oksida. Kod tako dobijenih materijala ispitivane su karakteristike pre i posle ozračivanja γ zracima. Dinamičko-mehaničkom analizom potvrđen je ojačavajući efekat punila.sr
dc.description.abstractThis work was aimed at the development procedure for the synthesis of polymer precursors network based on renewable raw materials. Developed a procedure for synthesis of poly lactide in solution, dichloro methane. The duration of the synthesis procedure was 6 h, and the success of the process was confirmed by the methods of identification and characterization of the obtained polymer PLLA. In this paper, the investigation obtained polymer materials, taking into account the idea of final destination, following methods were used: GPC (gel permeation Chromarography) to determine the distribution of molecular weight, IR spectrophotometry, showing the vibration of atomic, molecular or funkcionaknih group, and thermal analysis TGA and DSC, to track changes in a controlled heating and cooling. One of the aims of this study was to be given to review of existing theories of reinforcement fillers elastomer with nano particles, and examine the behavior of nano-composite materiajala under the influence of high energy radiation (gamma radiation). In the experimental part of elastomeric materials have been studied on the basis of butadienakrilonitrilnog rubber (NBR) and chlorosulphonated polyethylene rubber (CSM). CSM NBR mixing and forming the network system, which are used as precursors for a network of nano-composite particles ojačanaih active fillers-carbon black and silicon (IV) oxide. With so obtained materials were investigated characteristics before and after irradiation with γ rays. Dynamic-mechanical analysis confirmed the reinforcing effect of fillers.en
