Zusammenfassung:2-METHYLENE PROPANE PHOSPHONIC ACID ESTERS AND THEIR COPOLYMERS WITH ACRYLONITRILE ARE THE OBJECTS OF THE INVENTION. The fibers produced from the copolymers are flame-resistant and show increased thermal stability, improved affinity for dyes and fastness to light. The copolymers of acrylonitrile and 2-methylene propane phosphonic acid esters - in addition to other comonomers - are produced by polymerizing the monomers in solution or - preferably - in an aqueous suspension or emulsion. Formed articles, such as fibres from said copolymers can be prepared by spinning a solution of the copolymer in an organic solvent p.i. in dimethyl formamide.
