PROCESS FOR THE POLYMERIZATION OF ACRYLONITRILE

摘要

Polymerization of acrylonitrile alone or with a minor amount of other ethylenically unsaturated monomer conducted at above 120.degree.C., under the autogenous pressure or under pressure greater than the generated vapor pressure, and in the presence of 3 to 50 percent of water based on the weight of monomer(s) plus water. A polymer in substantially molten state is obtained allowing fiber, film and molded products to be produced directly without using solvents.
