Abstract
Provided is an acrylic syrup preparation method including the steps of: performing bulk photopolymerization by initiating a UV irradiation of a composition containing a photoinitiator and one or more types of acrylic monomers; stopping the UV irradiation at the time point when the temperature is increased by about 5° C. to about 40° C. from the time point when the temperature at which the UV irradiation of the composition is initiated; and purging the composition with an oxygen-containing inert gas after the UV irradiation is stopped.
