Abstract

Vacuole-free films, filaments and fibers consisting of a polymer mixture which comprises a copolymer of acrylonitrile and a polymer which is obtained by a polymer-analogue reaction of a polyacrylic acid ester with dimethylamine, said polymer containing from 40-99 mol % of N,N-dimethyl acrylamide units.
