Özet:

 In recent years, the usage areas of new graft copolymers synthesized from polymers have increased. Graft copolymerization is performed to reduce the weaknesses of polymers and expand their usage area. Graft copolymers are notable for their potential applications in wastewater treatment, biomedical, pharmaceutical, and nanomedicine fields. In our study, the free radical graft copolymerization method was used to eliminate the weak properties of sodium alginate ALG, chitosan CHI and polyvinyl alcohol PVA polymer. By grafting ethylene glycol dimethacrylate EGDMA monomer onto the polymers, sodium alginate-graft-polyethylene glycol dimethacrylate ALG-g-PEGDMA, chitosan-graft-polyethylene glycol dimethacrylate CHI-g-PEGDMA, polyvinyl alcohol-polymer-polyethylene glycol dimethacrylate PVA-g-PEGDMA graft copolymer was synthesized. The synthesis of graft copolymers was carried out using cerium ammonium nitrate CAN, ammonium persulfate APS and benzoyl peroxide BPO initiators in a nitrogen gas atmosphere at temperatures suitable for the initiators. The graft percentage and grafting efficiency of graft copolymers synthesized with different initiators were calculated from the mass increase. The lowest grafting results were obtained with the CAN starter. The grafting percentage 15 and grafting efficiency 6 of PVA-g-PEGDMA graft copolymer synthesized with CAN initiator were found. The highest grafting results were obtained with the BPO starter. Grafting percentage 116 and grafting efficiency 30 of ALG-g-PEGDMA graft copolymer synthesized with BPO initiator were found. The synthesized graft copolymers were characterized by Fourier transform infrared spectroscopy FT-IR and thermogravimetric analysis TGAdTG methods. The glass transition temperature Tg of the copolymers were determined.

 Son yıllarda polimerlerden sentezlenen yeni aşı kopolimerlerin kullanım alanları artmaktadır. Polimerlerin zayıf yönle azaltmak ve kullanım alanını genişletmek için aşı kopolimerizasyon yapılmaktadır. Aşı kopolimerler atık su arıtma, biyomedikal, farmasötik, nanotıp alanlarındaki potansiyel uygulamaları nedeniyle dikkat çekicidir. Çalışmamızda sodyum aljinat ALG, kitosan CHI ve polivinil alkol PVA polimerinin zayıf özelliklerini bertaraf etmek için serbest radikalik aşı kopolimerizasyon yöntemi kullanıldı. Polimerler üzerine etilen glikol dimetakrilat EGDMA monomeri aşılanarak sodyum aljinat-aşı-polietilen glikol dimetakrilat ALG-g-PEGDMA, kitosan-aşı-polietilen glikol dimetakrilat CHI-g-PEGDMA ve polivinil alkol-aşı-polietilen glikol dimetakrilat PVA-g-PEGDMA aşı kopolimeri sentezlendi. Aşı kopolimerlerin sentezi, seryum amonyum nitrat CAN, amonyum persülfat APS ve benzoil peroksit BPO başlatıcıları kullanılarak azot gazı atmosferinde başlatıcılara uygun sıcaklıklarda gerçekleştirildi. Farklı başlatıcılarla sentezlenen aşı kopolimerlerin aşı yüzdesi ve aşılama verimi kütle artışından hesaplandı. En düşük aşılama sonuçları CAN başlatıcısında elde edildi. CAN başlatıcısı ile sentezlenen PVA-g-PEGDMA aşı kopolimerin aşı yüzdesi 15 ve aşılama verimi 6 bulundu. En yüksek aşılama sonuçları BPO başlatıcısı ile elde edildi. BPO başlatıcısı ile sentezlenen ALG-g-PEGDMA aşı kopolimerin aşı yüzdesi 116 ve aşılama verimi 30 bulundu. Sentezlenen aşı kopolimerler Fourier dönüşümlü kızılötesi spektroskopisi FT-IR ve termogravimetrik analiz TGAdTG yöntemleri ile karakterize edildi. Kopolimerlerin camsı geçiş sıcaklıkları Tg belirlendi.
