## polymer phase-transfer catalyst

https://doi.org/10.1351/goldbook.PT07160
Polymer that acts as a phase-transfer @C00876@ and thereby causes a significant enhancement of the rate of a reaction between two reactants located in neighboring phases owing to its @C00874@ of the @E02301@ of one of the reactants across the @I03082@ to the other phase where the reaction takes place.
Note:
Polymer phase-transfer catalysts in the form of beads are often referred to as triphase catalysts because such catalysts form the third phase of the reaction system.
