METHOD OF PREPARING PRECURSORS FOR POLYACRYLONITRILE-BASED CARBON FIBERS |
摘要 |
PURPOSE: A method of manufacturing the polyacrylonitrile group precursor fiber for the carbon fiber is provided to maintain stability of a dope undiluted solution and to possibly manufacture high intensity/high elastic carbon fiber. CONSTITUTION: The method of manufacturing the polyacrylonitrile group precursor fiber for the carbon fiber is as follows. The dope undiluted solution uses more than 95% weight of acrylonitrile and less than 5% weight of polyacrylonitrile polymeric composition including comonomer. The dope undiluted solution manufacturing step is carried out at 25~50°C. Comonomer is composed of at least two kinds selected in a group consisting of methylacrylate, acrylic acid, methacrylic acid, itaconic acid. |
