It is shown that these polymers have very high complexing capacities with potassium and sodium ions and have good phase transfer catalysis activity.

In the new reaction system, product can easily isolate and catalyst can be recycled owing to the phase transfer catalysis character of catalyst in reaction process.

Methods Chalcone derivatives were synthesized from benzaldehyde derivatives and acetophenone by using weak alkali potassium carbonate as based catalyst in water via phase - transfer catalysis.
