Synthetic Polymers and their Uses

Synthetic Polymers are defined as man made polymers or plastics. First human made plastic was invented by Alexander Parks in 1855. It was then called Parke sine (later on Celluloid).

Polymers are made of small repeating structural units called monomers. Polyethylene is the simplest polymer, which consists of ethene (ethylene) as monomer units and the corresponding linear polymer is called high density polyethylene (HDPE).Many polymeric materials having chain-like structures similar to polyethylene are known. 

Synthetic polymers are often referred to as "plastics", well-known are polyethylene and nylon. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers. All of these are synthetic polymers.

Example of Synthetic Polymers and their Uses(bakelite :- a Thermosetting Plastic.)

Another important Synthetic polymer is Bakelite which is Phenol- Formaldehyde Resin. It is a thermosetting plastic. It is believed to be first true plastic. It can be melted and remolded again. It is cheap, durable and strong. It is very temperature resistant and so used in making cases for radios, telephones and clocks and also billiard balls. The most common grades of industrial phenolics are Canvas, Linen and Paper.

Uses of some General Synthetic Polymers with their Names and Monomer Units are as Follows.
