ABSTRACT:
An improved process for preparing increased molecular weight polyarylene sulfides is disclosed. The process comprises at least two stages: a first polymerization stage in which a polymer of a relatively low molecular weight is prepared and a second polymerization stage in which the molecular weight is substantially increased. The increased molecular weight permits the polymer to be used in a wide range of molding and shaping applications.
