Abstract
The activity of poly(oxyethylenes), terminated at both ends with phosp honium ion groups, as catalysts in phase transfer reaction has been co mpared with this of the nonionic analogs. The observed moderate enhanc ement of activity for diionically terminated poly(oxyethylenes) may be attributed to increasing alkali metal complexing ability, due to the intramolecular aggregation of the ionic end-groups resulting in the fo rmation of cyclic structure.
