Abstract

1.- process for obtaining filaments and threads of polyacrylonitrile high strength, by wet spinning, characterized in that first acrylonitrile is dissolved, along with a comonomer, in a highly concentrated aqueous saline solution of zinc chloride and sodium chloride and then polymerized in the presence of formaldehyde and hydrogen peroxide under the effects of ultraviolet light and the solution, thus obtained, is spun directly into a coagulation bath and the filaments and threads are transformed and then stretched in such a way that, by stretching during coagulation, an oriented structure of the skin is formed.
