摘要：
A method of quantifying the protection ratio of a hydroxyl group of a polymer compound, comprising calculating the protection ratio of a hydroxyl group of a polymer compound using a multiple regression calibration curve obtained by regression-analyzing main components of near infrared absorption spectra of a plurality of standards samples, from near infrared absorption spectra of samples containing a polymer compound composed of the following first structural unit and second structural unit: first structural unit: a structural unit of a structure having a hydroxyl group, second structural unit: a structural unit of a structure obtained by introducing a protective group into a hydroxyl group in the first structural unit. By this method, the protection ratio of a hydroxyl group of the polymer compound contained in a sample can be quantified with high precision in a short period of time without isolating the polymer compound.
