- DSC, Discovery 2500
Thermal analysis was performed using a Discovery 2500 DSC (TA Instruments, New Castle, DE) with a RSC 90 two-stage refrigerated cooling system. Sample (average mass or volume ± range) was sealed in aluminum [standard or hermetic] pans (purchased pan company) and loaded into the instrument at 40 °C [modify loading temperature, if temperature was changed from standard] with a reference pan of the same material. Under a constant flow of N2 gas (50 mL/min), the samples underwent [insert short description of your method; eg, three heat-cool-heat cycles between [range] °C with [time] minute isothermals between extremes.] DSC experiments and analyses were performed using the TRIOS (v.5.1.1) software from TA Instruments.
- TGA, Discovery 5500
Thermal analysis was performed using a Discovery 5500 TGA (TA Instruments, New Castle, DE). Sample was dried under dynamic vacuum for 24 h and stored in a desiccator prior to analysis [omit if this step was not performed prior to analysis]. Dried sample (average mass or volume ± range) was tared on a [aluminum, platinum, ceramic] pan (purchased pan company) and measured against a reference pan of the same material. Measurements were performed in nitrogen [modify background gas, if gas was changed from standard] from 25 to [maximum temperature] °C at [ramp rate] °C/min. [insert short method description here, including multiple temperature ramps and/or rates, isothermal events, or gas switching events] TGA experiments and analyses were performed using the TRIOS (v.5.1.1) software from TA Instruments.
- GPC, HFIP
Gel permeation chromatography (GPC) was performed using an Agilent Technologies 1260 Infinity series liquid chromatography system, including isocratic pump, autosampler, column compartment, and internal differential refractive index detector. Separation was performed on two Agilent PL-HFIP gel GPC columns (4.6 × 250 mm, 9 µm) in series, with preceding guard column of the same material (4.6 × 50 mm, 9 µm). Experiments were conducted with 100 uL injection volumes at 40 °C using a 20 mM solution of sodium trifluoroacetate dissolved in HPLC grade hexafluoroisopropanol (HFIP) as the mobile phase at a flow rate of 0.30 mL/min. Column calibration was performed with narrow-dispersity poly(methyl methacrylate) (PMMA) standards. Samples were prepared at 2 mg/mL [modify concentration, if changed from standard] in HPLC grade HFIP and left for 24 hours to diffuse into solution followed by 0.22 µm filtration.
- GPC, THF
Gel permeation chromatography (GPC) was performed using an Agilent Technologies 1260 Infinity series liquid chromatography system, including isocratic pump, autosampler, column compartment, and internal differential refractive index detector. Separation was performed on two Waters Styragel HR-4E GPC columns (7.8 × 300 mm, 5 µm) in series, with preceding guard column of the same material (4.6 × 30 mm, 20 µm). Experiments were conducted with 100 uL injection volumes at 40 °C using HPLC grade tetrahydrofuran (THF) as the mobile phase at a flow rate of 1.0 mL/min. Column calibration was performed with narrow-dispersity polystyrene (PS) standards. Samples were prepared at 2 mg/mL [modify concentration, if changed from standard] in HPLC grade THF and left for 24 hours to diffuse into solution followed by 0.22 µm filtration.
