Abstract: IN WHICH X IS ONE OF THE INTEGERS 1 TO 3, BY REACTING PURIFIED BUTUNE-2-DIOL-1,4 WITH ETHYLENE OXIDE IN THE PRESENCE OF BASIFYING AGENTS, THE IMPROVEMENT WHICH COMPRISES CARRYING OUT THE REACTION BY CHARGING THE BUTYNE-DIOL INTO AN AUTOCLAVE TOGETHER WITH A BASIC ION EXCHANGER RESIN AS BASIFYING AGENT AND FEEDING ETHYLENE OXIDE CONTINOUSLU TO THE AUTOCLAVE FOR FROM 8 TO 16 HOURS AT A REACTION TEMPERATURE OF RROM 45* TO 60*C. THE REACTION MIXTURE THEN BEING LEFT TO STAND AT SAID TEMPERATURE UNTIL THE PRESSURE REMAINS CONSTANT SAID ION EXCHANGER RESIN BEIN A PARTIALLY CROSSLINKED ORGANIC POLYMER BASED ON POLYSTYRENE AND DIVINYL BENZENE AS CROSS-LINKING COMPONENTS SAID POLYMER CARRYING NITROGEN-CONTAINING GROUPS OF THE FORMULAE
