SYNTHETIC POLYMERS Meaning and
Definition
-
Synthetic polymers are large, chain-like molecules composed of repeating subunits called monomers that are synthesized or created through human intervention rather than naturally occurring in nature. These polymers are artificially produced through chemical reactions in laboratories or industrial facilities, involving processes such as polymerization or copolymerization.
Unlike natural polymers which can be found in living organisms, synthetic polymers are specifically engineered to possess specific and desirable properties for various applications. These polymers can be designed to exhibit a wide range of characteristics, including high strength, flexibility, resistance to chemicals, heat resistance, electrical insulation, durability, and low cost of production.
Synthetic polymers are widely employed in numerous everyday products and industries due to their versatility. They are commonly used in the production of plastics, textiles, adhesives, coatings, foams, rubber, and various other materials. Examples of synthetic polymers include polyethylene, polypropylene, polyvinyl chloride (PVC), polystyrene, polyacrylonitrile, and polyethylene terephthalate (PET).
While synthetic polymers offer significant advantages, they can also have negative environmental impacts due to their non-biodegradable nature. Improper disposal or inefficient recycling of synthetic polymers can lead to pollution and environmental degradation. Hence, there is ongoing research and development to explore sustainable alternatives, such as biodegradable or recyclable polymers, in order to mitigate the environmental consequences associated with synthetic polymers.
Etymology of SYNTHETIC POLYMERS
The word "synthetic" originates from the Greek roots "syn" meaning "together" or "with" and "tithenai" meaning "to place" or "to set". It first appeared in the English language in the late 17th century, derived from the Latin word "syntheticus" meaning "made up of parts".
The term "polymer" is a combination of the Greek roots "poly" meaning "many" and "meros" meaning "part". It was coined in the mid-19th century by Jöns Jacob Berzelius, a Swedish chemist, to refer to substances made up of large molecules composed of repeating subunits.
Therefore, the phrase "synthetic polymers" refers to man-made large molecules made up of repeating subunits, with "synthetic" indicating that they are chemically synthesized or artificially produced.
