The amorphous form shows
WebThe logic behind making amorphous form is that it shows more solubility than the crystalline form. Amorphous form has more bioavailability compared to the crystalline form. The main disadvantage of this form is that it has excess of thermodynamic properties hence it tends to recrystallize into its crystalline form. WebSep 12, 2024 · 4.5: Crystallinity in Polymers. We often think of polymers in the form of plastics: solid materials that serve some structural function, like a water bottle or some Venetian blinds. Polymers are different from many other such solids. Metals, for instance, have crystalline structures, in which atoms form a regularly repeating pattern, row upon row.
