Abstract
This invention relates to a process for the preparation of acrylic polymers which are at least for the most part insoluble in water and have a high swellability in water, by reacting polyacrylonitrile or copolymers based on acrylonitrile at a temperature exceeding 100.degree. C. with aqueous-alkaline solutions which may contain an organic solvent which is miscible with water.
