The present invention relates to aqueous emulsions of polymers which contain 80 to 100 weight % of acrylonitrile polymerized within them, to a method for their preparation, and to their use as raw materials for acrylic and modacrylic fibres and as dyeing additives for adjusting the dyestuff affinity of cationic dyestuffs for conventional acrylic and modacrylic polymers and fibre materials produced from them. |
