Matrix Assisted Laser Desorption Ionization -Time of Flight (MALDI-TOF) analyses MALDI-TOF mass spectrometry analyses were performed on an Autoflex Speed TM (Bruker Daltonics). The molecular mass measurements were performed in the range of 1000 to 30000 m/z and in automatic reflectron mode using FlexControl TM 3.4 software. The equipment parameters were as follows: voltage values of ion sources #1 and #2 set as 19.00 and 16.95 keV, respectively; voltage values of reflectrons #1 and #2 set as 21.00 and 9.50 keV, respectively; lens tension 7.70 keV; pulsed extraction 450 ns; laser intensity between 70 and 80 %; smartbeam parameters set to ultra and sample rate; and digitizer settings set to 0.50 GS/s. The MS signals were acquired by summing 5,000 laser shots per spectrum. Prior to each analysis, the spectrometer was calibrated using PBPAC solution with the peaks corresponding to the cyclic polymer for with the respective masses (g•mol -1 ) of 2057. . Samples were prepared by mixing 6 µL of polymer solution (5 mg•mL -1 ) in THF with 20 µL of a 20 mg/mL DCTB matrix in THF and 2 µL of NaTFA solution at 6.8 mg•mL -1 in THF and
