Fluorimetry has been used to characterize ionomers synthesized by copolymerization ofmethyl mehacrylate, methacrylic acid and europium methacrylate (EMA). Under excita-tion of UV light at 375 nm no seif-quenching was found in fluorescence of EMA containingionomers at 615nm within the concentration range of 1.6×10-2 to 11.49×10-2 mol%.This means that the distance between two Eu3+ ions is larger than 5nm. In the sameconcentration range seif-quenching took place in europium octanoate (EOA) containing pply(methyl methacrylate) in which EOA was doped as an additive.
