Abstract

Improved process for the preparation of spinnable solutions, of polymers and copolymers with a high polyacrylonitrile content, of no more than 85%, by direct preparation of the polymer or copolymer solution starting from a mass including acrylonitrile in dimethylformamide, and preferably in association with other monomers, such as methyl methacrylate and sodium allylsulfonate, characterized by the fact that, under controlled temperature conditions, the process of polymerizing a mass containing a relatively high amount of monomer or monomers and stopping such a process is initiated only when a part of the aforementioned monomer or monomers has been converted, so that a suitable spinning solution is obtained for the formation of improved yarns in terms of their molecular weight and in regard to their whiteness characteristics.
