Synthesis and characterization of polymethacrylate nanoparticles via intramolecular crosslinking
Summary:
In this thesis, the synthesis of nanoparticles was explored. Initially we conducted the synthesis of the essential monomer, that was followed by the synthesis of the linear reactive polymeric chains via the Atom Transfer Radical Polymerization (ATRP) technique. This polymerization method, is considered as a well-control radical polymerization, which allows the synthesis of well-defined macromolecules. Moreover the use of high vacuum techniques in combination with the glovebox thechnique, provided a well controlled environment which enhanced the synthesis of well-defined products.
The monomers that we synthesized were the following: 9-anthryl methyl methacrylate and 9-anthryl methyl acrylate, and the reactive polymer that resulted were the homopolymer poly(9-anthryl methyl acrylate) the random copolymer poly(methyl methacrylate)-r-poly(9-anthryl methyl acrylate). Continuously the reactive linear polymers, were intramolecularly cross-linked in a high dilution solution using UV light radiation. The products were characterized structurally and molecularly by Gel Permeation Chromatography (GPC) and Nuclear Magnetic Resonance Spectroscopy (NMR).
After the radiation of the reactive linear chains, the nanoparticle formulation was confirmed via Size Exclusion Chromatography (SEC). Finally, Thermal Gravometric Analysis (TGA) and UV-vis measurements were conducted.
