Libraries with varying composition and exposure time were developed to enable high‐throughput analysis of conversion using FTIR spectroscopy. This technique was demonstrated by measuring viscosity and backbone chain structure effects using four monomers: DPGDA, TEGDA, bisphenol‐A‐glycidyl diacrylate and ethoxylated bisphenol‐A diacrylate. DPGDA has equivalent viscosity and double bond concentration with a shorter backbone chain length as compared to TEGDA. The ultimate conversion of TEGDA copolymerizations as compared to equivalent DPGDA copolymerizations is lowered from 15 to 5% due to differences in crosslink space chemistry and glass transition temperatures of the copolymer formulation.
