Results of the transesterification reaction of P(3-HB-co-4HB) by MCPA in the presence of 4-toluenesulfonic acid monohydrate (TSA · H2O).

aDetermined by GPC,bmolar percentage of pesticide attached to the oligomer chains, calculated from the 1H NMR spectra.* The amount of MCPA compared to that of P(3HB-co-4HB) used for the transesterification reactions, expressed in weight percent.P(3HB-co-4HB), Mn = 250000 g/mol and the dispersity index Mw/Mn = 2.5, 8.8 mol% of the 4HB unit content.Results of the transesterification reaction of P(3-HB-co-4HB) by MCPA in the presence of 4-toluenesulfonic acid monohydrate (TSA · H2O).
