Expert Solution
Step 1
Polymers are the repeating chains of monomer molecules. Polymers have unique properties like strength, toughness, etc. They depend on the type of bonding of the molecules and the bonding pattern. Polymers in general, bend, stretch like rubber and polyester and some are hard and tough like epoxides and glass.
