Comparison of the splitting fingerprints of individual resonances of13C NMR spectra of the block copolymer PHB- b -PHHx (A), random copolymer P(HB- co -HHx) (B), blend of PHB and PHHx (C), the first fraction (F1) of PHB- b -PHHx (D), and second fraction (F2) of PHB- b -PHHx (E). B and X refer to 3HB and 3HHx, respectively; numbering scheme was the same as that in Figure1. Chemical shifts are in ppm and tetramethylsilane (TMS) was employed as an internal chemical shift standard.
