Macromolecular crystallization useful considerations

Fig. 16. (a) Phase diagram of poly(ethylene oxide) 3,500/100,000 mol-wt mixtures at different concentrations. The open circles represent the calculation of and, calculated by using the Flory-Huggins equations 46 and 47, respectively. The filled symbols represent the experimental data, (b) Phase diagram of polyethylene dissolved in 1,2,4,5-tetrachlorobenzene (TCB). The experimental data were obtained by melting after crystallization. The macromolecular crystals, 2, were not at equilibrium, but melted considerably lower than (see Table 1).
