Title:
QUANTITATIVE METHOD OF RESIN COMPONENT
Document Type and Number:
Japanese Patent JP2018096980
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for individually determining contents of respective resin components even when the plurality of resin components contained in paste have nearly equal molecular weights and thermal decomposition temperatures.SOLUTION: The quantitative method for individually determining contents of respective resin components in paste including a plurality of resin components and inorganic powder, includes: a dissolution step of mixing the paste and an organic solution and dissolving the plurality of resin components; a separation step of separating the inorganic powder from the solution obtained by the dissolution step and forming a resin solution including the plurality of resin components; a measuring step of measuring the resin solution by pyrolysis gas chromatography and calculating respectively, peak area values of intrinsic pyrolysis products of the respective resin components generated by pyrolysis of the respective resin components; and a quantitative determination step of calculating the contents in the paste from the peak area values obtained in the measuring step on the basis of a calibration curve representing correlation between the contents of the respective resin components and the peak area values of the intrinsic pyrolysis products.SELECTED DRAWING: None
