ABSTRACT:
A process is provided for the stabilization of a fibrous material composed of an acrylic polymer, e.g. an acrylonitrile homopolymer or a closely related copolymer. The fibrous material is subjected to a multiple stage stabilization treatment in which the initial stage is conducted in an essentially inert atmosphere, and a subsequent stage in an atmosphere containing an appreciable quantity of oxygen. The initial treatment which is conducted in a relatively inert atmosphere is believed to result in an improved cyclized molecular structure without encountering excessive chain cleavage, and is followed by an oxygen cross-linking reaction. The stabilized product exhibits improved physical properties. Carbonized or carbonized and graphitized fibrous materials may be formed upon heating the stabilized product in an inert atmosphere.
