Deuterium labeled triblock copolymer

Figure 1 shows the right-hand side of Eq. 1 versus (Q Rg) i where Rg is the root-mean-square radius of gyration of the triblock copolymer subunit, for a 10% deuterium-labeled triblock copolymer, and of both branched polymer 2 and branched polymer 3. The branched polymers in Fig. 1 are made up of the triblock copolymer also shown in Fig. 1. As it happens, all the gel approximations give virtually the same curve that is shown for branched polymer 3 in Fig. 1. The infinite branched polymers shown in Fig, 1 have a more pronounced maximum in their scattering intensity curves than their constituent triblock copolymer, but the position of the maximum with respect to Q is hardly shifted at all. Figure 2 shows the same comparisons as Fig. 1, but now the triblock copolymers are 50% deuterated.
