Abstract

A method for setting conditions for use of a polymerization catalyst includes a step of acquiring a physical property value derived from remaining functional groups after maintaining a temperature of a composition including a polymerization-reactive compound and a predetermined amount of a polymerization catalyst, a step of calculating a remaining functional group ratio from the physical property value, a step of calculating a reaction rate constant based on a reaction rate equation from the remaining functional group ratio, a step of calculating an activation energy and a frequency factor from the reaction rate constant using an Arrhenius plot, a step of determining whether or not the activation energy satisfies a predetermined condition for the polymerization catalyst, an step of setting an approximation equation from the frequency factor, and a step of setting an addition range with respect to the polymerization-reactive compound.
