Difference between crystals and polymers
WebAboutTranscript. Polymers can exist as both crystalline and amorphous solids. In fact, most polymers are semicrystalline, which means that they contain a mixture of crystalline and amorphous regions. In this video, … WebThere are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers).

WebNov 1, 2024 · The glass transition is a property of only the amorphous portion of a semi-crystalline solid. The crystalline portion remains crystalline during the glass transition. At a low temperature the amorphous regions of a polymer are in the glassy state. In this state the molecules are frozen on place. They may be able to vibrate slightly, but do not ... WebCrystals demonstrate a repeated lattice structure which is where the long range order distinction comes from. The atoms pack close to each other in neatly organized units one after another. The bond lengths are uniform which allows a crystal to all melt at the same temperature (ie. melting point).
