Abstract

본 발명은 탄소섬유용으로 사용되는 폴리아크릴로니트릴계 전구체의 제조에 있어 소성시 작업성의 향상과 물성의 개선을 위해 특수 화합물이 함유된 수분산액을 사용하여 유제를 부여하는 것을 특징으로 한 것으로서, 구체적으로는, 하기 일반식(I)로 표현되는 폴리옥시에틸렌계 화합물을 물에 분산시켜 제조된 수분산액을 사용하여 유제를 부여함으로써, 특히 소성시 정전기 발생으로 인한 내염화섬유의 모우, 단사절 융착 및 접착으로 인한 섬유의 물성저하를 현저히 개선한 탄소섬유용 폴리아크릴로니트릴계 전구체의 제조방법에 관한 것이다.The present invention is characterized in that an emulsion is provided by using an aqueous dispersion containing a special compound for improving workability and physical properties during firing in the production of a polyacrylonitrile precursor used for carbon fiber, Specifically, by applying an emulsion using an aqueous dispersion prepared by dispersing a polyoxyethylene-based compound represented by the following general formula (I) in water, it is possible to prevent the generation of static electricity, The present invention relates to a method for producing a polyacrylonitrile precursor for carbon fibers which significantly improves the physical properties of fibers due to fusion and adhesion.
