<p>The process for producing sulphur-containing polymers, especially polyarylene sulphides, from at least one sulphide and at least one aromatic dihalogen compound in a solvent, takes place in the steps: a) a mixture of an aromatic dihalogen compound and a sulphide is polymerised; b) an aromatic dihalogen compound and a sulphide are added to the polymerised mixture; and c) the reaction mixture is further polymerised. The sulphur-containing polymers produced by the process are characterized by high purity and good mechanical properties.</p> |
