摘要： A polymer having pendant fluorescent groups is prepared by (trans)amidation of a preformed polymer by reaction with an amine-containing organic fluorescent composition of the Formula III ##STR1## wherein one of R.sub.5 and R.sup.6 may be hydrogen, and wherein within at least one of R.sub.5 and R.sub.6, or within R.sub.5 and R.sub.6 taken together, is an organic fluorescent group wherein the organic fluorescent group includes a polynuclear aromatic ring system. A degree of (trans)amidation derivatization of the polymer is accomplished by heating the admixture of polymer and fluorescent agent for a sufficient period of time. A second amine-containing post-polymerization derivatization agent other than the organic fluorescent composition of Formula III is added to the admixture or to at least a portion of the reaction product of the (trans)amidation derivatization, and is heated therewith to accomplish a degree of sequential or simultaneous post-polymerization derivatization with the second amine-containing post-polymerization derivatization agent.
