FIG. 7.
(a) Model prediction of the string mass L as a function of the fraction Φ of mobile-particles in the strings. Simulation results are given by the solid symbols, and the solid curve represents Eq. (11) with no free parameters. (b) Test of the living polymerization model relationship between the configurational entropy Sconf and Φ. We find excellent agreement with the predicted linear relation, Sconf ∝ (1 − ϕ). Note that, in the free association model of self-assembly,70 Sconf ∝ (1 − Φ)1/2, providing further evidence of the inadequacy of the FA model in describing glass formation.
