Melting process and the equilibrium melting temperature of polychlorotrifluoroethylene

open access: yesJournal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1962
A new method of estimating the equilibrium melting temperature, T(m), of a polymer is described, and applied to polychlorotrifluoroethylene (PCTFE). Experimentally determined values of the so-called observed melting point, [Formula: see text] , are plotted as a function of the isothermal crystallization temperature, T(x).
