Controlled post-polymerization modification through modulation of repeating unit reactivity: Proof of concept discussed using linear polyethylenimine example
Abstract
Post-polymerization modification (PPM) is a frequently used approach to alter polymer properties which cannot be achieved through direct polymerization of functional monomers. While well-defined polymeric materials can be obtained when the PPM is performed in an exhaustive manner, some applications require a partial polymer modification. The partial PPM approach typically uses kinetic or reactant ratio control and does not yield well-defined polymeric products. A proof-of-concept for a controlled PPM method, which is possible thanks to reactivity modulation of polymer repeating units (r.u.), is presented. The alkylation of fully N-methylated linear polyethylenimine (Me-L-PEI) is used as an example for the method and provides support for the controlled character of the process. Reactivity modulation, along the polymeric chain, is achieved thanks to the strong influence of already modified Me-L-PEI r.u
