    • In the spectrum of Figure 1c, peaks at 21.80 and 24.57 ppm are both assigned to the Sββ methylene carbon of the YEY sequence. The peak at 21.80 ppm has been already assigned to the Sββ carbon in the literature (ref 10, for E/Y copolymer from a heterogeneous Ti-based catalytic system. The assignment of the peak at 24.57 ppm to the S ββ carbon has been also reported in the literature (ref 11) for E/Y copolymers from a metallocene-based catalytic system (TBI, Copolymers reported in this work from CG- and EBTHI-based catalytic systems show for the first time the contemporary presence of both peaks. This aspect is elsewhere investigated and discussed ref 14
