Özet

Poly(4-vinylbenzyl-graft-ethylene glycol methyl ether) (poly(VB-g-mPEG)) amphiphilic graft copolymer was obtained using ‘click’ chemistry of polyethylene glycol methyl ether propargyl (mPEG-propargyl) and terminal azido poly(4-vinylbenzyl chloride) (PVB-N3). Using 2,2′-azobis(2-methylpropionitrile) and 4-vinylbenzyl chloride, poly(4-vinylbenzyl chloride) (PVBC) was created by free-radical polymerization (FRP). PVB-N3 was obtained using PVBC and sodium azide. Propargyl chloride and polyethylene glycol methyl ether were reacted to form mPEG-propargyl. The ‘click’ chemical method created poly(VB-g-mPEG) amphiphilic graft copolymer by reacting PVB-N3 with mPEG-propargyl. 1H-NMR, DSC, FTIR and GPC characterized the products. The spectroscopic and thermal studies monitored that poly(VB-g-mPEG) was built via combining FRP and ‘click’ chemistry.
