炭素材料製造用前駆体材料及びそれを用いた炭素材料の製造方法

Document Type and Number:

Japanese Patent JP7168909

Kind Code:

B2

Abstract:

To provide a carbon material precursor comprising an acrylamide-based copolymer having a high flame resistant yield, a high carbonization yield and a high total yield of flame resistance and carbonization even without blending an additional component such as an acid.SOLUTION: There is provided a carbon material precursor comprising an acrylamide/vinyl cyanide/unsaturated carboxylic acid-based copolymer which contains 40 to 99.8 mol% of acrylamide-based monomer unit, 0.1 to 35 mol% of vinyl cyanide-based monomer unit and 0.1 to 25 mol% of unsaturated carboxylic acid-based monomer unit.SELECTED DRAWING: None
