Abstract
Process for the preparation of acrylonitrile-based mixed polymerisates by anhydrous solution polymerization of at least 85% by weight of acrylonitrile-refered to the used weight of the polymerizable monomer compounds with copolymerizable monomer compounds unsaturated in ethylene and free of basic amino groups, characterized in that the mixed polymerization is carried out in a solvent consisting essentially of 12-dichloroethane and in the presence of polymerization catalysts soluble in 12-dichloroethane.
