Abstract
In a process for producing an acrylonitrile polymer melt in a substantially melted state by polymerizing a monomer mixture containing acrylonitrile in the presence of water at elevated temperature under increased pressure, the polymerization is carried out continuously using a persulfate as the polymerization initiator and under a particular forced stirring as defined in the specification. This process effectively suppresses runaway polymerization reaction, facilitates the melting of the resulting polymer, and in addition produces in an industrially advantageous manner a melt of an acrylonitrile polymer having a moderate molecular weight.
