PROCESS FOR CONTINUOUS PRODUCTION OF BRANCHED POLYARYLENE SULFIDES

摘要

A process for continuous production of branched polyarylene sulfides, which comprises pre-polymerizing a sulfur source with a dihalogenated aromatic compound to such an extent that the degree of conversion of the aromatic compound is below 95 % and polymerizing the obtained prepolymer in the presence of a branching agent while dispersing the prepolymer in a solvent phase in the form of globular droplets. The globular droplets of the prepolymer can be formed by adding the prepolymer to a solvent phase containing a phase separator previously added thereto.
