| Abstract: | The effects of methyl acrylate (MA) on heat-stabilization of acrylonitrile (AN) fiber were studied systematically in this paper. The results show that, when MA was used as comonomer, the cyclization of cyanic-group would be delayed, and the skin contents of PAN pre-oxidation fiber were increased with MA increasing. |
