摘要:
Acrylonitrile polymers of improved whiteness and thermal stability are provided by polymerizing acrylonitrile alone or with a comonomer in an aqueous medium, in the presence of a water-insoluble mercaptan, together with a redox catalyst comprising sulfurous acid or a salt thereof and nitrous acid or a salt thereof.
