For characterization of the chemical structure via proton nuclear magnetic resonance ( 1 H NMR) spectroscopy, the co-polymers were dissolved in deuterated chloroform in 40 mg/mL of concentration over the night and then filtered by passing through a pipette with cotton wool on the tip. To record spectra, a Bruker DPX 400 spectrometer (400 MHz) was employed with 128 scans and 1 s relaxation delay, and for reported chemical shifts, tetramethyl silane (TMS) was used as an internal chemical shift standard. The calculation of the molecular weight of the polymers and the experimental molar weight ratio of hard and soft segments was performed using reported formula. Gel permeation chromatography (GPC) was used to determine the average molar (apparent) mass (M ̅ n and M ̅ w) and molar mass dispersity, Ð (M ̅ w /M ̅ n) of obtained copolymers. HPLC Agilent 1200 series modular system with a refractive index detector (RID) was employed, equipped with two PLgel 5µm MIXED-C columns (300x7.5mm) connected in series to measure the molar masses of the samples. The samples were prepared in chloroform (CHCl3) with 3mg/ml of concentration and filtered through a 0.2µm polytetrafluoroethylene (PTFE) membrane. Data was recorded using "ChemStation for LC" and analyzed using "ChemStation GPC Data Analysis Software".
