Fourier transform infrared spectroscopy (FTIR) was performed by using BRUKER ALPHA Platinum apparatus (Germany) at room temperature in the range of 4000-600 cm -1 , at a resolution of 2 cm -1 and using 32 scans. Liquid (viscous) macromonomers were analyzed in transmission mode, after pouring samples between NaCl plates. Spectra of films after photocrosslinking were obtained using reflection mode and the ATR snap-in with diamond crystal. Spectra were analyzed using EZ OMNIC software.
