¹H and ¹³C NMR were performed on a Bruker DPX‐400 spectrometer, at 400 MHz and 100 MHz, respectively. All chemical shifts were in parts per million (ppm) relative to the tetramethylsilane (TMS) internal standard (0.03% v/v, 0.00 ppm). Coupling constants (J) were expressed in Hertz (Hz). Infrared spectra were recorded on a Bruker ALPHA platinum ATR Fourier transform spectrometer. Absorptions were recorded in wavenumbers (cm⁻¹). Mass spectrometry was achieved using an Agilent 6130B single Quad (ESI). GPC was performed on an Agilent 390‐MDS with autosampler using a PL gel 5.0 µm bead‐size guard column (50 × 7.5 mm), followed by two linear 5.0 µm bead‐size PL gel Mixed D columns (300 × 7.5 mm) and a differential refractive index detector. Using CHCl₃ as eluent the system was calibrated using linear poly(styrene) Easi Vial standards (Agilent Ltd) range from 162 to 5×10⁵ Da. Data were collected and analysed using Cirrus GPC/SEC (v. 3.3) and Agilent GPC/SEC software. TGA, DSC and melting points were carried out using Metler Toledo DSC1‐Star with 40 µL standard aluminium pans and autosampler. Samples heated from −100–70°C, cooled to −100 and heated from −100–600°C under N₂ atmosphere for DSC and heated from 25–600°C for TGA.

Number-average molar masses (M_n,SEC) and dispersity values (Ð) were determined using THF-SEC performed on an Agilent 390-MDS, comprising of an autosampler and a PLgel 5.0 μm bead-size guard column (50 × 7.5 mm²), followed by two linear 5.0 μm bead-size PLgel Mixed D columns (300 × 7.5 mm²) and a differential refractive index detector using THF (2% (v/v), TEA) as the eluent at 30 °C with a flow rate of 1 ml min⁻¹. The SEC system was calibrated with linear PS EasiVial standards (Agilent Ltd.) ranging from 162 to 105 g mol⁻¹. All samples were passed through 0.45 μm PTFE filter before SEC analysis. Molar masses were obtained by conventional calibration using ASTRA software.
