Date of data collection (single data, range, approximate date): 2017-2018 4. Geographic location of data collection: 2D SAXS data were collected at Argonne National Laboratory in Lemont, IL; all other data were collected at the University of Minnesota, Minneapolis, MN. 5. Information about funding sources that supported the collection of the data: Funding for this project was provided by the Center for Sustainable Polymers at the University of Minnesota, a National Science Foundation (NSF)-supported Center for Chemical Innovation (Grant CHE-1413862). -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Recommended citation for the data: --------------------- DATA & FILE OVERVIEW --------------------- Purpose Statement: This document describes the sample name convention used and the structure of file format. The document is organized by the type of data collected. General Notes: There are five folders containing data for the six different techniques used: NMR, SEC, DSC, SAXS, TEM, and tensile testing. There is an additional folder containing all of the ChemDraw files. All of the files contain labels corresponding to the sample names used in the manuscript (g100, g90, etc.). The files are then labelled with descriptions of the experiment; if the data are used in a specific figure, that figure name is also included in the file name. Files Contained: The files are saved in two different folders: one sorted by technique and one with all of the data for the figures. The data in both files are identical; it is sorted in this manner to facilitate searching for data by either categorization. NMR data: nuclear magnetic resonance (NMR) spectroscopy data is included for each sample. In each folder is the data as downloaded from the instrument. The .fid file can be opened in any NMR analysis software (e.g. MNOVA or iNMR). SEC data: size exclusion chromatography (SEC) data for all of the polymers is included in a single file. Each sample's data is output in two columns where the sample name is listed in the first row. The first column shows the elution time in minutes and the second column shows the dRI signal, with arbitrary units. All data are saved as a .csv file. DSC data: differential scanning calorimetry (DSC) data is included for the three different Figures that used DSC data (labeled both by figure and experiment). The files used to identify Tg's include two columns for each sample, the first is the temperature and the second is heat flow. The file used for qualitative aging has three columns for each sample and aging time (labelled in first row): first column is the temperature, second column is the enthalpy (heat flow data divided by the heating rate), 10 C/min or 0.1667 C/sec), and the third column is the enthalpy corrected for the PLA content. All data are saved as .csv file. SAXS data: small angle x-ray scattering (SAXS) data used to determine morphology had two columns per sample: first column is wavevector, q (in units of inverse angstroms) and second column is intensity (arbitrary units). All data are saved as .csv files. The 2D SAXS data is included as .tif files; both the raw data and intensity normalized data are included. The background scattering and MASK files are included, which are necessary to convert the raw data into the intensity normalized data. The meridionally and equatorially integrated 1D data are included in separate spreadsheets, where each sample had two columns: wavevector, q (units in inverse angstroms) and absolute intensity (units in inverse centimeters). TEM data: the transmission electron microscopy (TEM) images used throughout the manuscript are included. The folder of the unstrained samples contain multiple TEM images for each sample to show that the TEMs selected were representative. All TEMs are .tif or .jpg files. Tensile testing data: the tensile data is included in files sorted by the corresponding figures. Each sample (labeled in the first row with any additional necessary information) includes two columns: one for the engineering strain (units of %) and one for engineering stress (units of mega pascals). ChemDraw: the ChemDraw files for all schemes in the manuscript and supporting information are included as .pdf's. Are there multiple versions of the dataset? N -------------------------- METHODOLOGICAL INFORMATION -------------------------- Description of methods used for collection, generation, and processing of data: Additional supporting information, including documentation on the synthesis of model materials, is located with the published manuscript. People involved with sample collection, processing, analysis and/or submission: Michael Maher, Haley Schibur, Aristotelis Zografos, and Seamus Jones collected all NMR data and performed all synthesis. Ingrid Haugan, Seamus Jones, and Aristotelis Zografos collected all SEC and tensile testing data. Ingrid Haugan collected all DSC data. Bongjoon Lee collected all TEM data and collected and processed all SAXS data.
