“…Consequently, this transition enhances light transmission and activation efficiency, resulting in improved monomer reactivity, which is quantified by an increase in DC. Given that the DC is a crucial metric for evaluating the extent of curing and determining the final properties of the composite, 41,42 it mirrors the process of CC stretching during material formation, which is derived from changes in absorption peaks. Therefore, the mechanical properties of the hybrid‐filled samples, as observed in the multi‐scale mechanical tests described above, exhibit enhancements compared to large‐scale mono‐filled samples.…”

“…Degree of conversion and polymerization shrinkage are positively correlated 28,38) . For the radiant emittance exceeding 1,000 mW/cm 2 , analysis on polymerization kinetics through axial polymerization shrinkage measurement was a promising substitute for measuring degree of conversion using Fourier transform infrared (FTIR) spectroscopy, and transition times at which the maximum degree of conversion and strain rate occurred were similar 39) . In the present study, strong positive correlations were observed between peak times obtained temperature-heat flow, temperature-polymerization shrinkage, and heat flow-polymerization shrinkage measurements (Fig.…”

“…Monitoring of the polymerization reaction allows, among others, for quantitative studies of reaction kinetics, tracking molar mass changes and polymer molecular weight distribution, viscosity, degrees of branching, and many other parameters characteristic of polymer systems. [8][9][10] It also enables the optimization of reaction conditions and a critical evaluation of existing hypotheses and kinetic models used to describe polymerization reactions. Traditional off-line monitoring methods have many limitations, including time delay, mainly due to sampling and time-consuming qualitative and quantitative tests, which result in a significant time interval between sampling and obtaining the results of their analysis.…”
