The initiating species was prepared in situ in the charge. Since Li[B(C 6 F 5) 4] is insoluble in neat monomer, it had to be dissolved in a little toluene or in reality, the systems are only close-to-neat. It was found that isobutylene polymerizations can be readily initiated by adding Li[B(C 6 F 5) 4], dissolved in toluene or chloromethane, to neat monomer containing.

Abstract. Spectroscopy is an inevitable tool of characterizing polymer nanocomposites. Various spectroscopic techniques unveil the nature of dispersion of nanoparticles within the matrix polymer, the interactions between filler and polymer, functionalization of the polymer or nanofiller, interlayer spacing within the filler platelets, mechanical properties of the nanocomposites, etc.

Herein, we report the in situ synthesis of protein−polymer conjugates via reversible addition−fragmentation chain transfer polymerization (RAFT) as an efficient method. Further in situ functionalization of polymeric backbone is achieved via base-catalyzed maleimide – thiol addition at ambient temperature and its outcome is evidenced by a re-increased molecular weight in SEC, by virtue of decreased signal intensity of the 2-nitrobenzyl thioether moiety and the appearance of characteristic product protons in.

Synthesis provides the underpinnings for all advances in the science and engineering of polymeric materials. The past decade has produced many notable synthetic advances: the extension of living polymerization methods to new classes of reactive intermediates and new classes of monomers, the appearance of hyperbranched polymers, the controlled preparation of.

End groups are an important aspect of polymer synthesis and characterization. In polymer chemistry, end groups are functionalities or constitutional units that are at the extremity of a macromolecule or oligomer ().

In polymer synthesis, like condensation polymerization and free-radical types of polymerization, end-groups are commonly used and can be analyzed for.
