Four synthetic strategies to prepare well-defined polymeric materials with polar functional groups by ATRP are exemplified: direct polymerization of polar monomers, postpolymerization modification of monomer units, the use of functional ATRP initiators, and end-group chemical transformations.

520 $a Four synthetic strategies to prepare well-defined polymeric materials with polar functional groups by ATRP are exemplified: direct polymerization of polar monomers, postpolymerization modification of monomer units, the use of functional ATRP initiators, and end-group chemical transformations.
520 $a Chapter I presents a brief summary of all these methods. In Chapter II, rules for the rational selection of ATRP catalysts to mediate the polymerization of polar monomers are outlined. Particular attention is paid to the factors determining the activity of ATRP catalysts, stabilization of the catalysts towards the variety of side reactions often occurring in aqueous media or in the presence of polar monomers (such as disproportionation, loss of halide ligand from the ATRP deactivator, protonation in the case of ATRP of acidic monomers), and solvent effects. The rules for selection and design of ATRP catalysts are used in Chapter III to polymerize various polar monomers, including neutral, ionic, and acidic in protic (aqueous) media. Chapter IV describes the synthesis of well-defined copolymers of acrylonitrile and their use as precursors of carbon-based materials. In Chapter V, the polymers containing the polar acrylonitrile units are modified by a "click" reaction with azide to yield polymeric tetrazoles. Other click chemistry reactions, namely between organic azides and alkynes, are also illustrated in this Chapter. In the final Chapter VI, the preparation of polymeric materials (linear and hyperbranched polymers as well as gels with segmented structure) with disulfide groups by both the use of functional ATRP initiators and end-group chemical modifications is presented. The disulfide-containing polymers degrade reversibly upon reduction, which, along with the fact that they are highly halogen-functionalized (which allows further modifications) makes them materials of interest in controlled drug delivery and related biomedical fields.
