Polymer

A Polymer is a composition of a large molecule, generally formed by a long chain of chemical bond covalence.

Before the invention of artificial organic polymers, there was a massive usage of a plant polymer, generally known as “cellulose”. During the period of early 19th century cellulose was used in making of natural rubbers.

Major structure of Polymer

There are two key structures of Polymers, namely Cis and Trans. These two structures can not be altered by rotating physically. The first form develops when groups of substituents are belonging to the same side of carbon-carbon dual bond. The later Trans means the subustituents groups gathered on the opposite side of the double bond.

Structure of Cis and Trans

Various applications of Polymer

Polymer technology is a wide sphere including the different kinds of materials, integrated by long string of many repeat units. The major applications of Polymer are describe below:

Elastomers

Synthetic and natural rubber is the common examples of Elastomers. It has a loose cross-linked configuration. Generally, on average about 1 in 100 molecules are made a cross link. The rubbery material of Elastomers obtained from the bark of rubber trees.

Plastics

Basically Plastics are polymers; a varied group of synthetic material, under the proper pressure and temperature it can be shaped. It can be divided into two forms, thermoplastics and thermosetting plastics. These classes are made totally depending on their structure and chemical bonding.
Fibers

Fiber is very common application of polymeric materials. There are lots of examples of natural fibers like cotton, silk and wool, have been used from the early ages of civilization.
