A phenylene ether oligomer composition is disclosed comprising, a phenylene ether oligomer having an external amine content of less than or equal to 1.5 weight percent; and a residual solvent in an amount of 10 to 10000 parts per million by weight, based on the weight of the phenylene ether oligomer composition; wherein the phenylene ether oligomer composition has an intrinsic viscosity of 0.03 to 0.13 deciliter per gram; a glass transition temperature of 135 to 175° C., or a combination thereof.

A phenol alkylation catalyst exhibiting a desirable combination of activity, selectivity, and regenerability is prepared from a catalyst precursor that includes specific amounts of magnesium oxide, copper oxide or a copper oxide precursor, a hydrous magnesium aluminosilicate-containing binder, a pore-former, a lubricant, and water. Methods of forming and regenerating the catalyst, as well as a phenol alkylation method, are described.

A method for isolating a phenylene ether oligomer composition includes feeding a solution including a solvent and a phenylene ether oligomer into a thin film evaporator, forming a film on an interior surface of the thin film evaporator, and heating to devolatilize the solvent from the film, to provide a phenylene ether oligomer composition. The thin film evaporator includes cylindrical heating chamber and a rotor having one or more rotor blades, wherein an edge of the one or more rotor blades and the interior surface of the cylindrical heating chamber are separated by a distance of 0.5 to 3.5 millimeters. Phenylene ether oligomer compositions are also described.
