Stabilization and carbonization of acrylic fibrous material |
| abstract |
AN IMPROVED PROCESS IS PROVIDED FOR THE STABILIZATION OF AN ACRYLIC FIBROUS MATERIAL CONSISTING PRIMARILY OF RECURRING ACRYLONITRILE UNITS. THE FIBROUS MATERIAL IS SUBJECTED TO A STABILIZATION TREATMENT IN WHICH THE STARTING MATERIAL IS HEATED WHILE IMMERSED IN A SOLUTION OF A LEWIS ACID CAPABLE OF PROMOTING THE CYCLIZATION OF PENDANT NITRILE GROUPS, E.G. A SOLUTION OF STANNIC CHLORIDE. THE EXOTHERM NORMALLY EXHIBITED BY THE PRECURSOR UPON EXPOSURE TO HEAT MAY BE SUBSTANTIALLY REDUCED OR TOTALLY ELIMINATED IN A EFFICIENT MANNER BY SUCH TREATMENT WHICH IS BELIEVED TO RESULT IN A PRODUCT OF IMPROVED CHEMICAL STRUCTURE. THE RESULTING PRODUCT MAY BE DIRECTLY CARBONIZED OR CARBONIZED AND GRAPHITIZED IN AN INERT ATMOSPHERE OR ALTERNATIVELY NEXT SUBJECTED TO RELATIVELY MILD PREOXIDATION CONDITITIONS PRIOR TO TREATMENT IN AN INERT ATMOSPHERE. THE CARBONIZED OR CARBONIZED AND GRAPHITIZED FIBROUS MATERIALS EXHIBIT IMPROVED PHYSICAL PROPERTIES. |
