| Abstract | |
This project involves the study and development of composite materials (polymer / filler) nanostructured (nanocomposites), produced in an experimental polymerization unit, for the development of Nylon-6 (Polyamide-6 or PA-6) for new applications such as engineering plastics. The study involves the PA-6 and PA-6/organoclay nanocomposites polymerization process using 'ÉPSILON '-caprolactam monomer, as well as the production of organoclays. The blend is done in a batch reactor in which organophilizated and sodic bentonite are added to the reaction mass (polymeric matrix) during the polymerization process. The studies on the development of PA-6 and its nanocomposites with different characteristics intend to correlate the reaction and operational parameters to the final properties of the obtained polymer. Thus, simulation studies of the polymerization process were developed, along with experimental analysis of the product. In this sense, PA-6 and nanocomposites produced by the in situ polymerization process were evaluated taking into account the incorporation efficiency or the exfoliation rate of the clay in the polymer, the molecular weight of polymers / nanocomposites obtained and their thermal characteristics, determined by DSC and TGA analysis. Based on these results, the conclusion is that the in situ polymerization of PA-6 and PA-6/organoclay nanocomposites using the PA-6 hidrolitic polymerization process, is a viable process for the production of nano-composites, since it was observed through the DRX technique a possible formation of exfoliated and/or intercalary nanocomposites. In addition, the PA-6 polymerization process simulations, with or without the addition of clays, presented a good fit with the experimental values (AU) | |
