Abstract
The invention relates to a process for the production of crosslinkable polymers of acrylonitrile by polymerising acrylonitrile with a crosslinking component and optionally other comonomers in strongly polar organic solvents and in the presence of a peroxodisulphate and a 1,3-diketone as initiator system.
Claims1
A process for the production of spinnable solutions of crosslinkable copolymers of acrylonitrile which comprises solution polymerisation of at least 48% by weight of acrylonitrile, 0.5 to 12% by weight of a copolymerisable acid amide-N-methylol alkyl ether and, optionally, other copolymerisable comonomers in a strongly polar organic solvent and in the presence of a peroxodisulphate and a 1,3-diketone as catalyst system.
