Multi layer process for producing arylene sulfide polymers |
| abstract |
A process for producing a polyarylene sulfide polymer, which comprises reacting a polyhaloaromatic compound and a sulfidizing agent in a polar amide solvent in the presence of at least one polymerization additive to form a resinuous liquid consisting of a layer (I) containing a major amount of a polymer having a relatively high molecular weight and a minor amount of a polymer having a relatively low molecular weight and a layer (II) containing a major amount of a polymer having a relatively low molecular weight and a minor amount of a polymer having a relatively high molecular weight, and thereafter fractionating the layer (I) or layer (II) from the resinous liquid. |
