dc.description.abstract Chitin was grafted with poly(2-hydroxyrthyl methacrylate) poly(HEMA) by using ceric ammonium nitrate (CAN) as the initiator. The effect of temperature, time, concentration of the monomer (HEMA), the amount of chitin beads and the initiator (CAN) concentration on the grafting yield has been studied under nitrogen atmosphere. The optimum conditions for the grafting process were established. The maximum grafting percentage of poly(HEMA) on to non porous chitin was found to be 65%, while for porous chitin beads it was 515%. The optimum conditions were 0.1 g of porous chitin beads, 8 mL (3.3 Mol/L) HEMA monomer, 0.5 g (4.6×10-2 mol/L) of CAN initiator for three hour reaction time at 35 °C. The products were characterized by FT-IR, SEM, C13 NMR and XRD analysis. Swelling and dissolution behavior of the products were followed in different buffer solutions (pH = 1, 7 and 11). Keywords: 2-hydroxyethyl methacrylate (HEMA), chitin, graft copolymerization, hydrogel, chitin bead. en_US
dc.description.abstract ÖZ: Kitin redoks başlatıcısı serrik amonyum nitrat (CAN) ile poli (2- hydroksilmetilmethakrilat), poli (HEMA), ile aşılanmıştır. Sıcaklık, reaksiyon süresi, monomer konsantrasyonu, kitin ve başlatıcı madde, (CAN), konsantrasyonunun aşılama verimi üzerinde etkisi N2 atmosferi altında incelenmiştir.Aşılama işlemi için en uygun şartlar 0.1 g gözenekli kitin boncuklar kullanılarak 35°C sıcaklıkta, üç saatlik bir reaksiyon süresi için, 8 ml (3.3 mol / L), HEMA monomer, 0.5 g (4.6 x 10-2 mol/L) CAN başlatıcı olarak bulundu. Aşılama yüzdesi gözenekli kitin boncuklarda en fazla 515% gözenekli olmayan kitin boncuklar içinse %65 olarak bulunmuştur. Ürünler FT-IR, SEM, C13 NMR ve XRD analizi ile karakterize edildi. Şişme ve çözelti içindeki davranışları farklı pH lardaki tampon çözeltilerde (pH = 1, 7 ve 11) takip edildi.
