## Abstract Biobased thermosets resins were synthesized by functionalizing the triglycerides of epoxidized soybean oil with methacrylic acid, acetyl anhydride, and methacrylic anhydride. The obtained resins were characterized with FTIR, ^1^HβNMR, and ^13^CβNMR spectroscopy to confirm the functional

tion. Complex simultaneous equations required in providing quantitative results from direct spectrophotometric readings are no longer necessary.
- Since the results are calculated from measurements taken at all wavelengths, confidence in the reliability of the final result is considerably increased.
I t is a time-saving technique with a degree of accuracy comparable to chemical or microbial analytical methods.
This technique is more suited to pharmaceutical control than to regulatory laboratories. However, end points can be evaluated easily and accurately in the presence of background absorb-4.
703 ance, even when its nature is unknown to the analyst. Now that recording spectrophotometers are more readily available in various models and price ranges, it is our conviction that this analytical approach holds real promise and will be used in most control laboratories, pharmaceutical and otherwise.
