Polymer that acts as a phase-transfer catalyst
and thereby causes a significant enhancement of the rate of a reaction between two reactants located in neighboring phases owing to its catalysis
of the extraction
of one of the reactants across the interface
to the other phase where the reaction takes place.
- 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.
