Question

How are Polymers and Crystals are similar and different?

Answer 1

Both are cases where molecules pack together in an orderly fashion. In crystals, molecules pack together in any direction. The molecules are not chemically bonded together. In polymers, long chains of the same molecule are chemically bonded together.

Answer 2

Polymer whose molecular structu re 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.
