What are the difference between a crystalline structure and an amorphous structure?

Answer 1

I do not know of any polymers that are 100 percent crystalline. This is because most of the polymers you can make or buy have different molecular weights. So unlike small molecules, there are some differences in sizes between polymers. These differences prevent the polymer from being able to pack perfectly. This is the main reason why crystalline polymers also have amorphous regions.

Answer 2

Polymer whose molecular structure lacks a definite repeating form, shape, or structure is called amorphous polymer and has no definite shape while the polymer in which a unit structure repeats itself is called crystalline in nature and has a definite shape, form and structure.

Answer 3

crystalline phase is exactly what it sound like. After years of stress within intense gravity and increased density in some cases a period of crystallization occurs, just like the quartz that is abundant here on earth and other places through increased heat from the bombardment of meteorites. Just like a diamond comes into being through years of pressure coal after thousands of years will crystallize and become a diamond. For the question of amorphous phase of a polymer, I can only imagine it is the stage between a gas and a solid polymer which in most cases is a man made substance such as plastic.

Answer 4

• A crystalline solid has a pattern of atoms or molecules that, baring defects, could repeat infinitely.
• An amorphous solid has no such pattern.

Answer 5

Amorphous structures do not have the neat arrangement of atoms found in the crystalline structure of minerals.
