These reactions are also VERY HELPFUL in adding FUNCTIONAL GROUPS to molecules that are less active.

All About Polymers

Think about this for class discussion:- discuss potential use of polymers in gardening - design a humidity sensor made out of a polymer - discuss natural versus synthetic polymers, the concepts related to polyethylene chains(e.g., linear polyethylene, branched polyethylene, cross-linked polyethylene)

A polymer is a large molecule, or macromolecule, composed of many repeated subunits, known as monomers. Because of their broad range of properties,[4] both synthetic and natural polymers play an essential and ubiquitous role in everyday life.[5] Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals. - Wikipedia
