Figure 9 Scaling relationship between root-mean-square radius and molecular weight for polystyrene using GPC/MALLS. (From Wyatt, P. Hicks, D. L., Jackson, C., and Wyatt, G. K., Am. Lab., 20, 108,1988. With permission.)...

Figure 6. Log M versus local root-mean-square radius for a broad polystyrene standard (-----) and narrow polystyrene standards (m).

Problem 4.18 For the polystyrene sample in Problem 4.17 calculate (a) the second virial coefficient, (b) the root mean square end-to-end distance, and (c) the root-mean-square radius of gyration. 

Figure 5.1 The root mean-squared radius of gyration, (Rq), of polystyrene of molecular weight M = 1.2 X 10 g/mol in Decalin as a functmn of temperature. (From Nose, T. and Chu, B., Macromolecules, 12, 1122, 1979. With permission.)...

Concentration and molecular weight dependences of the probe radius of gyration Rg for molecular weight P probes in solutions of molecular weight M matrix polymers as functions of matrix concentration c. The fits are to stretched exponentials Rgo exp(—ac"), with the percent root-mean-square fractional fit error %RMS, the materials, and the reference. Materials include EB-ethyl benzoate, PMMA-polymethylmethacrylate, pS-polystyrene.
