600 MHz ¹H NMR spectrum of copoly(LGTBE-LGDBE3-18) in CDCl₃ at room temperature with and . The proportion of LGDBE3-18 units in the copolymer was calculated to be 4.7 mol% from the comparison of the integration values of the H2 signals. LGTBE: 2,3,4-tri-O-benzyl 1,6-anhydro-β-D-glucopyranose, LGDBE3-18: 2,4-di-O-benzyl-3-O-octadecyl 1,6-anhydro-β-D-glucopyranose.
