METHODOLOGICAL INFORMATION

Description of methods used for collection, generation, and processing of data:
Bruker Avance III HD 500 was used for 1H and 13C NMR spectroscopy, and molar masses were calculated using end-group analysis. General NMR parameters are as follows: solvent: Chloroform-D, number of scans (ns): 32, relaxation delay (d1): 10s. The average molar mass values and molar mass distributions were analyzed by SEC using an HFIP mobile phase on an EcoSEC system HLC-8240GPC series liquid chromatograph through two Tosoh TSKgel SuperAWM-H columns at 40 �C and a flow rate of 0.35 mL min�1 and equipped with a refractive index detector. Molar masses and dispersities were determined by conventional calibration against poly(methyl methacrylate) (PMMA) standards. Thermal properties were obtained by differential scanning calorimetry (DSC) measurements using a TA Instruments Discovery Series differential scanning calorimeter equipped with a liquid nitrogen cooling accessory. All samples (ca. 4�9 mg) were analyzed under a nitrogen atmosphere in hermetically sealed T-Zero aluminum pans. Samples were first heated to 240 �C at 10 �C min-1 and held for one minute to erase any thermal history (first heat cycle). The samples were then cooled to �80 �C at 10 �C min-1, followed by heating to 240 �C at the same rate (second heat cycle). All reported data was collected from the second heating cycle unless otherwise indicated.
Polymers were melt-pressed between two Teflon sheets in a Wabash Hydraulic Press at 215 �C. The materials were pressed at 300 lbs. pressure for 2 min and at 3300 lbs. pressure for an additional 2 minutes before being rapidly quenched (~35 �C min�1) to room temperature using water cooling. Dog-bone-shaped tensile bars were punched out after the films were allowed to rest at RT for a minimum of 48 h, resulting in samples with approximately 0.5 mm thickness, 2.5 mm gauge width, and 14 mm gauge length. Tensile testing experiments were conducted using a Shimadzu Autograph AGS-X Tensile Tester and an extension rate of 50 mm min�1 until material failure. Extensional dynamic mechanical thermal analysis (DMTA) and stress relaxation experiments were performed on a TA Instruments RSA-G2 in tension mode on rectangular polymer films with 0.5 mm thickness and ~2.0 mm gauge width. Temperature control was achieved using a nitrogen atmosphere. DMTA experiments were conducted with an oscillatory strain of 0.1% and angular frequency of 1 Hz at a heating rate of 5 �C min�1. For stress relaxation experiments, samples were equilibrated at the desired temperature for 10 min before application of a 25% step strain, and the modulus was measured for 104 s (3 h). The results of the stress relaxation studies were normalized for comparison across trials. SAXS and WAXS experiments were conducted at the DuPont-Northwestern Dow Collaborative Access Team (DND-CAT) synchrotron research center Sector 5-ID-D of the Advanced Photon Source at the Argonne National Laboratory.
