A process for preparing halogen-terminated oligomers by an Ullmann condensation is disclosed wherein a diphenol and a dihalobenzene are reacted in the presence of cuprous oxide in 2,4,6-collidine. The oligomers are useful in producing acetylene-terminated resins by replacing the terminal halogen atoms with acetylene groups.
