Bu proje, preseramik polimerlerin sentezi, karakterizasyonu ve polipropilen ile hazırlanan kompozitlerinin alev geciktirici özelliğinin araştırılması üzerine yapılan çalışmaları içermektedir. Öncelikle, poli(metilsilin), poli(metilsilseskuoksan) ve poli(dimetilsilan) polimerleri sentezlenmiştir. Sentezlenen preseramik polimerler FTIR, 1H-NMR, UV-VIS, DSC, TGA ve SEM analizleri ile karakterize edilmiştir. Karakterizasyon sonuçları bu üç polimerin de başarıyla elde edildiğini göstermektedir. Daha sonra, polipropilen ve bu polimerler ağırlıkça belirli yüzdelerde sinerjist katkılarla birlikte veya haricinde, çift vidalı bir ekstrüderde proses edilmiştir ve enjeksiyonlu kalıplama yöntemi ile kalıplanmıştır. Kompozitler yanma ve mekanik testlerine tabi tutulmuş ve ayrıca TGA, DSC ve SEM analizleri ile karakterize edilmiştir. Sınırlayıcı oksijen endeksi (LOI) verilerine dayanarak en iyi sonuçlar poli(metilsilseskuoksan) ve poli(dimetilsilan) polimerleri ile oluşturulan kompozitlerde elde edilmiştir. Saf polipropilenin 17.5 olan LOI değeri, herhangi bir mekanik özellik kaybına yol açmadan preseramik polimer ve sinerjistlerin eklenmesiyle 22 değerine ulaşmıştır.

Effect of polymer additives on the physical properties of bitumen based composites Doğan, Mehmet; Bayramlı, Erdal; Department of Polymer Science and Technology (2006) Polymer modified bitumen is a binder obtained by the incorporation of various types of polymers in bitumen using mechanical mixing or chemical reactions. There are several factors affecting the properties of polymer modified bituminous composites such as; chemical composition of bitumen, kind of polymer and filler, compatibility of bitumen and polymer, amount of bitumen, polymer and filler, particle size of filler and process conditions. The main objective of this study is to determine the effects of polyme...
Flame retardancy of polymer nanocomposites Işıtman, Nihat Ali; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2012) This thesis is aimed to understand the role of nanofiller type, nanofiller dispersion, nanofiller geometry, and, presence of reinforcing fibers in flame retardancy of polymer nanocomposites. For this purpose, montmorillonite nanoclays, multi-walled carbon nanotubes, halloysite clay nanotubes and silica nanoparticles were used as nanofillers in polymeric matrices of poly (methyl methacrylate) (PMMA), high-impact polystyrene (HIPS), polylactide (PLA) and polyamide-6 (PA6) containing certain conventional flame...
Pyrolysis mass spectrometric analysis of copolymer of polyacrylonitrile and polythiophene Oğuz, Gülcan; Hacaloğlu, Jale; Department of Polymer Science and Technology (2004) In the first part of this work, the structural and thermal characteristics of polyacrylonitrile, polyacrylonitrile films treated under the electrolysis conditions in the absence of thiophene, polythiophene and the mechanical mixture and a conducting copolymer of polyacrylonitrile/polythiophene have been studied by pyrolysis mass spectrometry technique. The thermal degradation of polyacrylonitrile occurs in three steps; evolution of HCN, monomer, low molecular weight oligomers due to random chain cleavages a...
Studies on polylactide nanocomposites with polyhedral oligomeric silsesquioxane Meyva Zeybek, Yelda.; Kaynak, Cevdet; Department of Polymer Science and Technology (2020) The main purpose of the first part of this thesis was to investigate influences of three parameters on the mechanical and thermal properties of the polylactide (PLA) matrix nanocomposites filled with polyhedral oligomeric silsesquioxane (POSS) particles. For the first parameter of “Filler Content”, nanocomposites with 1, 3, 5, 7 wt% basic POSS structure were compared. For the second parameter of “Functional Group”, basic POSS structure having only nonpolar isobutyl groups were compared with three other func...
Toughening of polylactide by blending with various elastomeric materials Meyva, Yelda; Kaynak, Cevdet; Department of Polymer Science and Technology (2014) The purpose of the first part of this thesis was to investigate influences of three different ethylene copolymers on the toughness and other properties of very brittle biopolymer PLA (polylactide). For this aim, PLA was melt blended by twin-screw extruder with various amounts of ethylene vinyl acetate (EVA), ethylene methyl acrylate (EMA) and ethylene-n-butyl acrylate-glycidyl methacrylate (EBA-GMA). SEM and DSC analyses indicated that these ethylene copolymers were thermodynamically immiscible with phase s...
