Polymer and Composite

• A polymer is a substance made up of many repeating units (called monomer units). Polymers are usually distinguished by a high molar mass (formula weight), often ranging into thousands or millions of grams per formula unit.

• Polymerization is the process by which monomers (smaller chemical units) are combined to form a polymer.

• Example : polyethylene, polypropylene, natural rubber, cellulose, carbohydrate and lignin.
