PURPOSE:To obtain a high-fluorescent strength titled polymer with fluorescent group in its main chain, by dissolving a fluorescent compound in one of two liquids mutually insoluble and toluylene-2,4-diisocyanate in the other followed by carrying out an interfacial polymerization. CONSTITUTION:The objective polymer can be obtained by dissolving a fluorescent compound selected from thionine, safranine T, acridine yellow and phenosafranine in one of two liquids, i.e., hydrophilic and hydrophobic ones mutually incompatible or insoluble, and toluylene-2,4-diisocyanate in the other, preferably stirring, followed by carrying out an interfacial polymerization (pref. at 0- 40 deg.Cfor 5-30min).
