<P>PROBLEM TO BE SOLVED: To provide a method of measuring the epoxy equivalent of an epoxy group containing resin or a composition containing it, capable of easily and quickly performing measurement at a low cost. <P>SOLUTION: The method includes: a process of measuring refractive indexes of the plurality of epoxy group containing resins whose epoxy equivalents are known or the compositions containing them and preparing the analytical curve of the epoxy equivalents and the refractive indexes of the plurality of epoxy group containing resins or the compositions containing them; and a process of measuring the refractive index of the epoxy group containing resin of an object to be measured, whose epoxy equivalent is unknown, or the composition containing it, and calculating the epoxy equivalent of the epoxy group containing resin of the object to be measured or the composition containing it on the basis of the analytical curve by the refractive index. <P>COPYRIGHT: (C)2012,JPO&INPIT |
