The studies show that the rate of maximum polymerization was found to increase with increase in concentration of photoinitiator while a decrease was observed by an increase in temperature. The final conversion showed a decrease at highest isothermal condition due to vitrification. Estimation of kinetic parameters including applicability of autocatalytic and modified autocatalytic models were investigated by nonlinear regression. It was observed that the modified models gave a better fit with the experimental data and kinetic parameters showed a decrease with increase in temperature and an increase with increase in concentration of photoinitiator.</p>10aAutocatalytic model10akinetics10aLevenberg-Marquardt method10aPhotopolymerization1 aHarikrishna, Reghunathan1 aPonrathnam, S.1 aRajan, C., R.1 aTambe, S., S.  uhttps://library.ncl.res.in/content/photopolymerization-bis-aromatic-and-alicyclic-based-solid-urethane-acrylate-macromonomer-0
