Abstract

Abstract

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.
