Abstract

Synthesis of poly epichlorohydrin-g-ethylene glycol [poly ECH-g-EG ] graft copolymer was reported by means of "click" chemistry. For this purpose, epichlorohydrin ECH was polymerized by using H2SO4 via cationic ring-opening mechanism. Propargyl polyethylene glycol-1000 propargyl PEG-1000 was synthesized by the reaction of polyethylene glycol PEG with 1000 Da and propargyl chloride. Terminally azide polyepichlorohydrin PECH-N3 was obtained by reaction of poly epichlorohydrin PECH and sodium azide. By using PECH-N3 and propargyl PEG-1000, poly ECH-g-EG graft copolymers were synthesized. The graft copolymers were relatively obtained in high yield. The characterization 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, thermogravimetric analysis, and fractional precipitation [solvent THF, mL /non–solvent petroleum ether, mL ] techniques. This method which is used for polymer synthesis is simple, effective, eco-friendly and has low energy consumption.

Özet

Poli epiklorhidrin-g-polietilen glikol [poli ECH-g-EG ] graft kopolimerlerin sentezi “click” kimyası metodu ile rapor edilmektedir. Bu amaçla, epiklorhidrin ECH , H2SO4 ile katyonik halka-açılması polimerizasyonu üzerinden polimerleştirildi. Propargil polietilen glikol-1000 propargil PEG-1000 , propargil klorür ve 1000 Da molekül ağırlığına sahip polietilen glikolün PEG reaksiyonu ile sentezlendi. Poliepiklorhidrin azit PECH-N3 , poliepiklorhidrin ve sodyum azidin reaksiyonu ile elde edildi. PECH-N3 ve propargil PEG-1000 kullanılarak poli ECH-g-EG graft kopolimerler nispeten yüksek verimle sentezlendi. Ürünler, fraksiyonlu çöktürme [çözücü THF, mL /çöktürücü petrol eteri, mL ] ile saflaştırıldı; nükleer manyetik rezonans spektroskopisi, Fourier transform infrared spektroskopisi, gel geçirgenlik kromatografisi, elemental analiz ve termogravimetrik analiz cihazları kullanılarak karakterize edildi. Polimer sentezi için kullanılan bu metot basit, etkili, çevre dostu ve düşük enerji tüketimine sahiptir
