Summary
Time resolved fluorescence technique was used to demonstrate physically the ionpair aggregation phenomena in the ionomers containing fluorenylsodium as the pendant group along the polymer chains in THF at 25°C. It was found that ionpairs in the ionomer with mole fraction of fluorenylsodium equal to 0.02 did not associate to form stable aggregate. However, the ionpairs would aggregate in those ionomers with higher fluorenylsodium contents. In the homopolymer of vinylfluorenylsodium, extensive aggregation of the ionpairs was observed.
