The article presents the results of studies of the features of photorecovery of trifunctional and tetrafunctional phosphorus-containing methacrylates with various spacers in the structure. It was found by differential scanning calorimetry that the introduction of spacers leads to a decrease in the overall thermal effect of the UV-curing process in comparison with a spacerless sample. With the help of a photocell for an E7-25 immittance meter, which is capable of recording changes in dielectric properties over time, the influence of the spacer and its structure on the degree of completion of the UV-curing process was determined. The effect of the introduced spacer on the formation of a crosslinked polymer is shown, which is manifested by different times of the induction period.
