The dataset includes DSC (polymer melting point and crystallinity), GPC (polymer molecular weight and molecular weight distribution), nuclear magnetic hydrogen spectroscopy (characterization of polymer structure content), nuclear magnetic carbon spectroscopy (characterization of polymer regularity), and XRD data. Each data file has been renamed according to the format in the manuscript. For example, the file named Table 1 run 1 in the DSC data file is the DSC data of the sample numbered run 1 in Table 1 of the manuscript, and other data is the same. The nuclear magnetic hydrogen spectrum and carbon spectrum data need to be used in conjunction with the MestReNova software. The data collection period is from March 2023 to November 2023,
