Title:
METHOD FOR MEASURING DEGRADATION OF CRYSTALLINE POLYMER
Document Type and Number:
Japanese Patent JP2018100943
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for measuring degradation of a crystalline polymer, the method allowing detection of the degradation of a crystalline polymer in an initial stage.SOLUTION: The method for measuring degradation of a crystalline polymer includes the steps of: measuring a Raman spectrum of a crystalline polymer; and comparing the measured Raman spectrum and the Raman spectrum of a regular sample and measuring the peak shift of a predetermined peak caused by a precursor phenomenon in which a part of the amorphous phases in the lamella structure of the crystalline polymer is going to crystallize.SELECTED DRAWING: Figure 1
