Schematic illustration of how oligomers were used to produce the σ-profile of polymers: (a) a trimer of the homopolymer PVA (32,000 g mol–1, Nunits = 726) and (b) a tetramer of the copolymer EUD (212,000 g mol–1, Nunits,A = Nunits,B = 1140). The structures were drawn by GaussView98 and post-processed in Inkscape.99
