This question is designed to evaluate your technical knowledge and hands-on experience with various analytical techniques used in polymer science. When answering, mention specific techniques such as spectroscopy (e.g., FTIR, NMR), chromatography (e.g., GPC), thermal analysis (e.g., DSC, TGA), and mechanical testing (e.g., tensile testing). Provide examples of how you have used these techniques in your previous research or projects to analyze polymer properties. Highlight any specialized equipment you are proficient with and discuss the significance of these techniques in understanding polymer behavior and properties.
Example:
"In my previous role, I frequently used FTIR spectroscopy to identify functional groups in polymer samples. Additionally, I employed GPC to determine the molecular weight distribution of synthesized polymers. For thermal properties, I utilized DSC to measure the glass transition temperature and TGA for thermal stability analysis. I also conducted tensile testing to evaluate the mechanical strength of polymer films. These techniques allowed me to comprehensively characterize the polymers and make informed decisions in the development process."
