FT-IR/UATR and FT-IR Transmission Quantitative Analysis of PBT/PC Blends
Polymer Testing, 2020 Abstract Polymer blends are produced to achieve properties that pure polymers are unable to. The qualitative analysis of these blends is not always satisfactory to point out failures in the final product and, therefore, the determination of their content might be required.
