| abstract |
Polyarylene thioether is easily prepared by oxidative polymerizing an aromatic compound of the formula: ##STR1## wherein R 1 , R 2 , R 3 and R 4 are independently a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group, and Y is a hydrogen atom or a group of the formula: ##STR2## wherein R 5 , R 6 , R 7 and R 8 are independently a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group and X is --O--, --S--, a methylene group or an ethylene group with a sulfidizing agent in the presence of an acid and an oxidizing agent, or in the presence of an acid, a catalyst for oxidative polymerization and oxygen, or in the presence of a Friedel-Crafts catalyst. |
