POLYACRYLONITRILE BASED COPOLYMERS FOR CARBON FIBER PRECURSORS AND THE METHOD OF PREPARATION THEREOF
The present invention relates to a polyacrylonitrile-based copolymer for a carbon fiber precursor and a method for preparing the same, and more particularly, to a novel polyacrylonitrile-based copolymer for a carbon fiber precursor, which is prepared based on a dicyclohexylammonium-2-(carboxymethyl)...

| description | The present invention relates to a polyacrylonitrile-based copolymer for a carbon fiber precursor and a method for preparing the same, and more particularly, to a novel polyacrylonitrile-based copolymer for a carbon fiber precursor, which is prepared based on a dicyclohexylammonium-2-(carboxymethyl)acrylate (DCMA) comonomer containing 1 to 1.5 mol of dicyclohexyl amine and 0.75 to 1 mol of triethyl amine based on 1 mol of itaconic acid, and a method for preparing the same. Accordingly, a novel polyacrylonitrile-based copolymer for a carbon fiber precursor, which has a high carbon conversion rate, can be provided through the above method, and the novel polyacrylonitrile-based copolymer for a carbon fiber precursor can be used for a carbon fiber having improved thermal stability and strength. |
