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

Abstract: 1. THE WATER-SOLUBLE, HIGHLY OXYETHYLATED, SYNTHETIC POLYMIDE CONTAINING CHEMICALLY COMBINED ETHYLENE OXIDE IN AN AMOUNT OF AT LEAST 10 TIMES THE WEIGHT OF THE POLYAMIDE PORTION, SAID OXYETHYLATED POLYAMIDE BEING OBTAINED BY REACTING. (A) A LOWER-DEGREE OXYETHYLATED POLYAMIDE, WHICH CONTAINS AT LEAST 50% BY EIGHT OF COMBINED ETHYLENE OXIDE, AND WHICH HAS BEEN PREPARED BY REACTING A SYNTHETIC LINEAR POLYAMIDE HAVING RECURRING -CO-NH-GROUPS IN THE BACKBONE WITH FROM 2.5 TO 10 TIMES ITS WEIGHT OF ETHYLENE OXIDE IN THE PRESENCE OF AT LAST ONE INERT LIQUID SOLVENT SELECTED FROM THE CLASS CONSISTING OF ALIPHATIC AND CYCLOALIPHATIC HYDROCARBONS, SAID SOLLVENT BEING INERT UNDER THE REACTION CONDITIONS AND HAVING NO SOLVENT OR SWELLING ACTION ON THE POLAMIDE OR ON THE OXYETHYLATED POLYACTION ON THE POLYAMIDE OR ON THE OXYETHYLATED POLYC. AND AT ATMOSPHERIC OR SUPERATMOSPHERIC PRESSURE IN THE ABSENCE OF ANY OXYETHYLATION CATALYST, WITH (B) AT LEAST 10 TIMES ITS WEIGHT OF ETHYLENE OXIDE IN THE PRESENCE OF SAID INERT HYDROCARBON SOLVENT, AT A TEMPERATURE OF FROM 60*C. THE 150*C. AND AT ATMOSPHERIC OR SUPERATMOSPHERIC PRESSURE IN THE PRESENCE OF AN OXYETHYLATION CATALYST.
