The reactivty of poly(glycidyl methacrylate), obtained by RAFT controlled radical polymerization, has been investigated with a nucelophilic agent, such as morpholine, in various aprotic polar solvents in order to optimize the reaction (time and nucleophile excess). A strong interaction between polymer and solvent, gained by hydrogen bonds, during the process has proved to be essential in order to lower the reaction time and the nucelophilic agent excess. Dissimilar behaviors have been detected by GPC analysis due to the reactivity of the sulfhydryl formed during the RAFT's aminolysis. The various solvents lead to conditions in which different inter and intra-chain associations occur; the result is the formation of dimers, trimers and tetramers (to a less extent) in the first case, and cyclical structures in the second one. The reactivity of the hydroxy group, formed during the ring opening reaction, has been further investigated in order to link isothiocyanate-functionalized fluorescent marker along the polymeric chain.
