Blending of nylon 56 with elastomers. Characterization and properties

Abstract

This research project explores the properties resulting from the combination of nylon 5,6 with natural rubber. The results underline the challenges involved in obtaining a homogeneous blend, highlighting the complexities of interactions between the components. A satisfactory blend was achieved by obtaining a Brabender. To briefly describe the main methods employed, analysis by Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) confirmed the semi-crystalline nature of nylon 5,6 and the amorphous nature of rubber. In addition, thermogravimetric analysis (TGA) identified degradation residues, suggesting the possible commercial origin of the polymer. Mechanical tests revealed that, although nylon alone resisted higher stress, the blend offered greater deformability. Polarized light microscopy revealed morphological changes, while the addition of natural rubber decreased the crystallization rate of nylon 5,6. Overall, this study makes a significant contribution to our understanding of polymer blends, offering innovative perspectives for a variety of industrial applications.
