Abstract
A method for setting polymerization condition includes a physical property acquiring step of, when heating a composition including a polymerization-reactive compound and a polymerization catalyst and/or a polymerization initiator and retaining heat at a predetermined temperature, acquiring a physical property value a derived from a functional group before heating of the polymerization-reactive compound and a physical property value b derived from a remaining functional group after maintaining a temperature for a predetermined time; a remaining functional group ratio calculating step of calculating a remaining functional group ratio from the physical property value a and the physical property value b; a reaction rate coefficient calculating step of calculating a reaction rate coefficient from the remaining functional group ratio on the basis of a reaction rate equation; and a polymerization temperature calculating step of calculating a polymerization temperature on the basis of the reaction rate coefficient and conditions below.
