Abstract

In the present work, a family of functionalized statistical copolymers was synthesized by radical polymerization from a varied composition of benzyl methacrylate (BzMA) and N,N-dimethylaminoethyl methacrylate (DMAEMA) comonomers using 2,2’-azobisisobutyronitrile (AIBN) as initiator. The characterization, identification, and composition analysis of each copolymer were carried out by spectroscopic methods (FTIR and 1H-NMR). Then, different properties were evaluated: molecular size was determined by measurement of intrinsic viscosity [η] in THF at 25 °C and glass transition temperature (Tg) analyzed by differential scanning calorimetry. Films were prepared by the solvent casting method from selected samples with different compositions and their mechanical properties were analyzed by tensile tests. It was observed that the composition of the functionalized copolymers substantially affects their macromolecular and mechanical properties, evidencing greater flexibility when the DMAEMA content in the copolymer increased.

期刊介绍： The scope of the journal is to publish original contributions and reviews on studies, methodologies, instrumentation, and applications involving the analysis and characterization of polymers and polymeric-based materials, including synthetic polymers, blends, composites, fibers, coatings, supramolecular structures, polysaccharides, and biopolymers. The Journal will accept papers and review articles on the following topics and research areas involving fundamental and applied studies of polymer analysis and characterization: Characterization and analysis of new and existing polymers and polymeric-based materials. Design and evaluation of analytical instrumentation and physical testing equipment. Determination of molecular weight, size, conformation, branching, cross-linking, chemical structure, and sequence distribution. Using separation, spectroscopic, and scattering techniques. Surface characterization of polymeric materials. Measurement of solution and bulk properties and behavior of polymers. Studies involving structure-property-processing relationships, and polymer aging. Analysis of oligomeric materials. Analysis of polymer additives and decomposition products.
