Process for the production of polyacrylonitrile spinning solutions having stable viscosity
Spinning solutions, having stable viscosity, of acrylonitrile (co)polymers are obtained by adding polymer additives having a molecular weight Mn of 1000 to 100000 and a content of 1 to 27 equivalents of basic nitrogen/kg of polymer additive in an amount of 0.01 to 2% by weight, based on acrylonitril...
