Abstract: There are disclosed a novel copolymer comprising having recurring unit represented by the formula: ##STR1## wherein Y represents a phenylene group or a naphthylene group, with a recurring number of k and a recurring unit represented by the formula: ##STR2## wherein Ar represents a divalent aryl group, with a recurring number of l, a value of k/(k+l) is 0.5 to 0.97 and having a reduced viscosity [.eta..sub.sp/c ] of 0.3 dl/g or higher as measured in p-chlorophenol solution at a concentration of 0.2 g/dl at 60.degree. C., and a process for producing the novel copolymer comprising the steps of:(a) reacting dihalogenobenzonitrile represented by the following formula: ##STR3## wherein X represents a halogen atom, an alkali metal salt of hydroquinone or dihydroxynaphthalene represented by the following formula:MO--Y--OM (IV) wherein Y represents a phenylene group or a naphthylene group and M represents an alkali metal, and an alkali metal salt of a divalent phenol represented by the formula:MO--AR--OM (V) wherein in Ar represents a divalent aryl group and M represents an alkali metal, in the presence of a solvent, and(B) treating the obtained reaction product with water or an alcohol.
