Anionic Polymerization IX: A Review of the Use of Crown Ether as a Modifier in the Anionic Polymerizct for researchers. This is due to the fact that crown ether possesses the ability to form complexes with a variety of inorganic salts and also the ability to solubilize these salts in aprotic solvents. The complexation between metal cation and crown ether is believed to involve ion-dipole interacti

Synthesis of Ultrahigh Molecular Weight Nylon 4 with Onium Salt and Crown Ether-Containing Catalystspreparation, physico-chemical characterization, and utilization of the polymer. The great interest in this polymer is due to the fact that nylon 4 textile fibers combine the good strength properties of nylon 6 or 66 with the hydrophilicity of cotton..

Synthetic Reactions by Gas-Liquid Phase-Transfer Catalysisth gas-liquid chromatography (GLC) in that anion transfer processes and partition equilibria between gaseous and liquid phases both take place and affect the synthesis. Using GL-PTC, nucleophilic substitution reactions have been so far carried out under operative conditions and with synthetic result
