Özet
Bu tez kapsamında, keten tohumu yağı otooksidasyona uğratılarak otookside polimerik keten tohumu yağı (PKY) elde edildi. Otooksidasyon işlemi gün ışığı altında, hava oksijeni ile oda sıcaklığında gerçekleştirildi. Elde edilen PKY, tersiyer bütil akrilat (tBA) ve metil akrilat (MA) monomerleri ile ayrı ayrı serbest radikal polimerizasyonuna (SRP) uğratıldı ve PKY-g-PtBA ve PKY-g-PMA graft kopolimerleri sentezlendi. Polimerizasyon kinetiği incelendi. Elde edilen graft kopolimerlerin yapısal karakterizasyonları; nükleer manyetik rezonans (1H NMR), fourier transform infrared spektrofotometre (FT-IR), jel geçirgenlik kromatografisi (GPC) ile incelendi. Termal karakterizasyonları ise; termal gravimetrik analiz (TGA) ve diferansiyel taramalı kalorimetri (DSC) teknikleri kullanılarak incelendi.
In the scope of this thesis, polymeric linseed oil (PLO) was obtained by autooxidation of linseed oil. Autooxidation process was carried out under daylight, with air oxygen at room temperature. The obtained PLO was separately subjected to free radical polymerization (FRP) with tertiary butyl acrylate (tBA) and methyl acrylate (MA) monomers, and PLO-g-PtBA and PLO-g-PMA graft copolymers were synthesized. Polymerization kinetics were examined. Structural characteristics of the graft copolymers obtained were examined by nuclear magnetic resonance (1H NMR), fourier transform infrared spectrophotometer (FT-IR), gel permeation chromatography (GPC). Thermal characterizations were analyzed using thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) techniques.
