Polymers

Polymer is a large molecule which is on chemical analysis reveals many sub units that are repeated across the chain of molecules. Their broad range of properties in both their types (synthetic and natural) play a very essential universal role in everyday life applications.

Detailed Description for Polymers



A polymer structure can be simply visualized by thinking of a metal chain. In the same way the polymer at the atomic level are bonded to each other to form links in the polymer chain. These chains are termed ‘repeat units’ which are formed form one or more molecules that are known as monomers.

The polymer chemistry consists of the repeated units that can vary distinctively based on the raw ingredients that builds the polymer. For example, polyethylene. The polymer that is used in the production of a wide range of plastic bags and containers is made up of a very simple repeat unit comprising of two carbon atoms bonded to one another to form a single link.

PROPERTIES

·       Polymers are made of long flexile chains which can be easily tangled. The disordered tangling of a polymer chain is what gives its structure the name amorphous.

·       Polymers when stretched form crystalline arrangements because the chains of polymers line up side by side to form an organized structure. The crystalline arrangement can also be obtained through slow cooling, where an individual polymer chains fold over on themselves.

·       Polymers can also be modified to create huge three-dimensional cross linked chains. The result is essentially one huge molecule of polymer.

APPLICATIONS

·       Ethene can polymerise to form polyethylene which is used to make plastic bags, shopping bags, plastic bottles.

·       Styrene can polymerise to form polystyrene which is typically used for insulation and protective packaging.

·       Polymers are mostly used to make transparent kitchen cling films.

·       Industries such as automotive, aerospace, medicine, building, consumer goods and packaging make use of the products that use polymers as raw material.

·       It is also used to produce structural adhesive, fillers, fibres, emulsion, resins, inks and pigments.

·       It is used to produce playground equipment, balls, golf clubs, swimming clothing.

·       It is used to produce protective helmets that is used in various applications.

·       Polymer nanofiber is used in electrical conductors and sensor devices that is used to sense cells, arteries and veins.

·       Teflon, a type of polymer is used as a coating to kitchen utensils.
