Özet

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 H2SO4via 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.

Abstract

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 propargilPEG-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.
