Polymer characterization is the process of analyzing and understanding the properties and structure of polymers. This includes examining their molecular weight, composition, and physical properties such as elasticity, thermal stability, and solubility. Techniques like gel permeation chromatography and differential scanning calorimetry are commonly used to gather this information. The results of polymer characterization help scientists and engineers predict how a polymer will behave in different applications. By understanding these properties, they can tailor polymers for specific uses, such as in packaging materials, automotive parts, or medical devices, ensuring optimal performance and durability.
