The present disclosure relates to a process for producing homogeneous solutions comprising dissolved polyacrylonitrile-based polymer, and a system suitable therefor. The homogeneous polymer solutions produced by the process described herein may be used for producing carbon fiber, typically carbon fiber used in manufacturing composite materials.

Process for the production of homogeneous solutions of polyacrylonitrile-based polymer

The present disclosure relates to a process for producing one or more carbon fiber precursor fibers, particularly by spinning a polymer solution, wherein the polymer has a polydispersity (PDI) of less than or equal to 2, in a coagulation bath with a jet stretch of about 5 to about 60. The one or more carbon fiber precursor fibers produced may be used for producing carbon fiber, typically carbon fiber used in manufacturing composite materials.

Process for preparing carbon fibers from low polydispersity polyacrylonitrile

The present disclosure relates to a process for producing carbon fibers utilizing a salt of an organic cation containing C═N imine group, and carbon fibers produced by such process.

Process for producing carbon fibers and carbon fibers made therefrom

The present disclosure relates to the control of the degree of swelling of polymer fiber, such as polymer fiber used in the manufacturing of composite materials, by control of the pH of the coagulation bath during spinning.

Controlling the degree of swelling of polymer fibers during coagulation

A polymer comprising repeating units derived from a first monomer, typically acrylonitrile, and repeating units derived from a second monomer different from the first monomer, wherein the second monomer is a compound comprising an ethylenically unsaturated organic anion and an organic cation containing a C═N imine group; a process for producing carbon fibers using the said polymer; and carbon fibers made therefrom, are described herein.
