150 MHz ¹³C NMR spectra of copoly(LGTBE-LGDBE3-18)s in CDCl₃ at room temperature. (a) Poly(LGDBE), (b)–(e) copoly(LGTBE-LGDBE3-18)s with the proportion of LGDBE3-18 units of 1.3, 22.2, 46.9, and 72.9 mol%, respectively, and (f) poly(LGDBE3-18), in which polymers are corresponding in Table 1. The signals were assigned by a combination of H-H COSY and HMQC measurements.
