Mechanism of phase-transfer catalysis using glycidyl methacrylate-ethylene dimethacrylate copolymers modified with tributylammonium groups in nucleophilic displacement reactions

Glycidyl methacrylate-ethylene dimethacrylate resins modified with tributylammonium groups show improved phase-transfer catalysis activity due to swelling in both aqueous and organic phases, but not through balancing hydrophilic and hydrophobic properties.
