15, 16 The results of the degradation are presented in Figure . A 2.5 wt% solution of TBD in THF was used for the degradation of both poly(S-co-POT) and for poly(MA-co-POT) during one hour at room temperature. Both polymers showed an important decrease of the Mn and PS oligomers of DP close to 20 were obtained. This value is in rather good agreement with the theoretical one with 5 mol% of POT. For poly(methyl acrylate), the length of oligomers is slightly higher (DP close to 60), suggesting a lower random incorporation of thioester moieties than during the copolymerization with styrene. This result nevertheless confirmed that statistical incorporation of POT occurred during the copolymerization of the two vinylic monomers. This also confirms the better efficiency of POT than DOT to copolymerize with styrene and acrylate.
