Abstract

Synthesis of poly vinyl chloride–g–ethylene glycol [poly VC–g–EG ] graft copolymers was carried out by me- ans of “click” chemistry of propargyl polyethylene glycol propargyl PEG and terminally azide polyvinyl chloride PVC–N3 . Primarily propargyl PEG was synthesized by the reaction of PEGs 3000 Da, 2000 Da, 1500 Da, 1000 Da, 600 Da, and 400 Da with propargyl chloride. PVC–N3 was obtained by reaction of purified PVC and sodium azide. By using PVC–N3 and propargyl PEG, poly VC–g–EG graft copolymers were synthesized. The primary parameters such as concentration, and time that influenced the reactions were assessed. The charac- terization of products was accomplished by using multi instruments and methods such as nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, gel permeation chromatography, elemental analysis, and fractional precipitation [non-solvent petroleum ether, mL /solvent THF, mL ] techniques.

“Click” Kimyası ile Poli vinil klorür–graft–etilen glikol Graft Kopolimerlerin Sentezi ve Karakterizasyonu

Abstract

Poli vinil klorür–g–etilen glikol [poli VC–g–EG ] graft kopolimerlerin sentezi propargil polietilen glikolün propargil PEG ve azit son uçlu polivinil klorürün PVC–N3 “click” kimyası vasıtasıyla gerçekleştirildi. Öncelikle propargil PEG, çeşitli molekül ağırlığındaki PEG’ler 3000 Da, 2000 Da, 1500 Da, 1000 Da, 600 Da ve 400 Da ile propargil klorürün tepkimesi sonucunda sentezlendi. PVC–N3, saflaştırılmış PVC ve sodyum azit tepkimesi ile elde edildi. Poli VC–g–EG ] graft kopolimerler, PVC–N3 ve propargil PEG kullanılarak sentezlendi. Derişim ve zaman gibi tepkimeyi etkileyen temel parametreler değerlendirildi. Ürünlerin karakterizasyonları nükleer manyetik rezonans spektroskopisi, Fourier transform infrared spektroskopisi, gel geçirgenlik kromatografisi, elemental analiz ve fraksiyonlu çöktürme [çözücü THF, mL /çöktürücü petroleum ether, mL ] gibi yöntemler kullanılarak incelendi
