Abstract
Alpha-omega-Diglycidyl-oligoethylenoxides were prepared by reacting al pha-omega-dihydroxy-oligoethylenoxides with epichlorohydrin. They were then crosslinked with triethylenetetramine to form catalyst beads whi ch were tested for their liquid-solid phase-transfer catalyst activity in the reaction of 1-bromobutane with potassium phenoxide. Regardless of the oxyethylene chain length, the catalyst beads showed significan t activity, which was relatively high for oligomers with a great numbe r of oxyethylene repeating units.
