WebCrystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In a gas, the relative positions of the atoms or molecules are completely random. WebJun 1, 2002 · The degree of crystallinity is then defined as (1) X c = Δ H f (T m )/ Δ H f o T m o where Xc is the weight fraction extent of crystallinity, Δ Hf ( Tm) is the enthalpy of fusion measured at the melting point, Tm, and Δ Hfo ( Tmo) is the enthalpy of fusion of the totally crystalline polymer measured at the equilibrium melting point, Tmo.
