摘要：

A detailed analysis of available crystal size-crystallization temperature data for crystallization of poly (ethylene) from dilute solutions indicates that all of the data may be represented by the semi-empirical expression: {Mathematical expression}. For good solvents, Ts0=110.5 °C, σe=72.0 erg cm-2, and {Mathematical expression}. This semi-empirical expression differs from theoretical expressions, l*=2σeTs0/ΔhfΔTc+δl, only in the magnitude of δl predicted (5-15 Å) relative to the empirical value of {Mathematical expression}. One possible origin of this difference may be a temperature dependence of σe. © 1968 Dr. Dietrich Steinkopff Verlag.
