Ion polymerization
Web4 apr. 2024 · Precipitation polymerization is a non-homogeneous technique that starts with homogeneous system where both initiator and monomer are completely soluble but formed polymer is insoluble and therefore precipitates. Examples of polymers synthesized through precipitation polymerization include TFE, ACN, etc. [ 31, 32, 33, 34, 35, 36 ]. WebIon-containing membranes were constructed using a single-step microemulsion polymerization. In addition to conventional characterization, their ionic conductivities …

WebAccording to Fuoss and Winstein et al., 1,2 anions may associate in two different ways: they may either be tightly associated with the cations or they may be loosely associated with solvated counterions. Winstein et al. named these two types of ion pairs contact ion pairs (CIP) and solvent-separated ion pairs (SIP).
