Abstract: | Summary Free radical copolymerization of acrylonitrile (AN, M1) with poly(2,6-dimethyl-1,4-phenylene oxide)- -vinylbenzyl ether (PPO-VBE, M2,
n + 4200g/mol,
w/
n + 1.04) was performed at 60°C in either a mixture of N,N-dimethylformamide/toluene or tetrahydrofuran, using 2,2 -azoisobutyronitrile (AIBN) as initiator. The characterization of the resulting polyacrylonitrile grafted with poly(2,6-dimethyl-1,4-phenylene oxide) (PAN-g-PPO) was performed by 200 MHz 1H-NMR spectroscopy and solubility. |
