STUDIES ON THE CYCLIZATION MACHANISM OF POLYACRYLONITRILE (PAN) CATALYZED BY TIN-TETRACHLORIDE
The cyclization machanism of polyacrylonitrile(PAN) catalyzed by Yin-tetrachloride has been studied in the present paper. The experimental results show that the catalytic reaction is through the succesive co mplexation betty een tin atom in SnCl4 and CN group in PAN. The suggested cyclization machanism is described in the following.
