Acrylic fibers and films which particularly are suited for thermal stabilization
Abstract
Abstract AN IMPROVED PROCESS IS PROVIDED FOR THE PRODUCTION OF STABILIZED ACRYLIC FIBERS AND FILMS. A MINOR QUANTITY OF AN ALKALI METAL SALT OF AN ORGANIC SULFONATE IS PROVIDED IN INTIMATE ASSOCIATION WITH AN ACRYLIC FIBROUS MATERIAL OR FILM AND IS INCORPORATED THEREIN IN A NON-POLYMERIZED FORM. UPON HEATING (PREFERABLY WHILE PRESENT IN AN OXYGEN-CONTAINING ATMOSPHERE) THE THERMAL STABILIZATION REACTION IS PROMOTED BY THE PRESENCE OF THE ALKALI METAL SALT OF AN ORGANIC SULFONATE. THE RESULTING STABILIZED FIBROUS MATERIAL OF FILM IS FLEXIBLE AND NON-BURNING, AND MAY BE UTILIZED A FIRE RESISTANT FIBER, FABRIC OR FILM, OR OPTIONALLY CARBONIZED OF CARBONIZED AND GRAPHITIZED TO FORM A CARBONACEOUS FIBROUS MATERIAL OR FILM.
