Polythene, nylon, polyester, and bakelite are examples of polymers with an emphasis on their monomers and applications.
Commercially Important Polymers
There are a variety of commercially important polymers that are utilised in a variety of fields of research, industry, and technology. Here are a few examples:
Nylon
Nylon is a lab-created synthetic polymer that is mass-produced by businesses due to its commercial value. In the textile and fabric business, it is widely used. Nylon belongs to the linear polyamides family.
Nylon 6 and nylon 6,6 are two kinds of nylon that are regularly used. Adipic acid and hexamethylenediamine are used to make Nylon 6,6 (which is frequently used as a fibre). They have a molecular structure that is compact and resistant to abrasion. Hydrogen bonds bind the monomers together. Strength, shine, suppleness, and resistance to oil and chemicals are some of the features that make nylon such a useful material.

Nylon Fibre: Nylon Fibre is used in shirts, underwear, raincoats, lingeries, and other clothing/apparel. Nylon is used in the manufacturing of conveyor belts, seat belts, nets and ropes, parachutes, and tents.
Bakelite
Bakelite is one of the first polymers ever created by humans. It’s a thermosetting polymer with excellent strength and the ability to keep its shape after being moulded. It was one of the earliest polymers/plastics to be developed in a lab. Condensation of formaldehyde with phenol produces the polymer. (C6H6OCH2O)n is its chemical formula.
Bakelite is often used for producing electrical switches because of its great resistance to heat and chemicals, as well as its low electrical conductivity. Bakelite is also used to produce a variety of utensil handles. It is one of the most significant and widely utilised polymers for the manufacture of numerous components and parts. Pipe stems are another application for this material.
Polyethylene
Polyethylene (PE) is a light, flexible synthetic resin derived from ethylene polymerization. Polyethylene is a polyolefin resin that belongs to the major polyolefin resin family. It is the world’s most frequently used plastic, found in everything from clear food wrap and shopping bags to detergent bottles and automotive fuel tanks. It can also be sliced or spun into synthetic fibres, or made to have rubber-like elasticity.
Chemical structure and molecular makeup
Ethylene (C2H4) is a gaseous hydrocarbon made by breaking ethane, which is a major component of natural gas or can be distilled from petroleum. Ethylene molecules are made up of two methylene units (CH2) joined by a double bond between the carbon atoms, as seen in the formula CH2=CH2. The double bond can be broken and the extra single bond utilised to attach to a carbon atom in another ethylene molecule under the influence of polymerization catalysts. Ethylene has the following chemical structure:
Polyester
Polyester is a synthetic fabric made primarily from petroleum. This fabric is one of the most widely used fabrics in the world, with thousands of consumer and industrial applications.
Polyester is a polymer that is mostly made up of compounds with the ester functional group. Ethylene, a component of petroleum that can also be produced from other sources, is used to make most synthetic and some plant-based polyester fibres. While certain types of polyester are biodegradable, the majority are not, and polyester manufacture and use contribute to global pollution.
Polyester may be the only component of garment products in rare cases, but polyester is more commonly combined with cotton or another natural fibre. The use of polyester in clothing cuts production costs, but it also reduces comfortability.
When polyester is blended with cotton, it improves the natural fiber’s shrinkage, durability, and wrinkling properties. Polyester fabric is extremely resistant to the elements, making it excellent for long-term usage in outdoor settings.Like Polyester Fabric Bath Curtain Cactus Shower Curtain
Despite this, polyester is still one of the most extensively used fabrics in the world, and it’s difficult to locate consumer clothing that doesn’t include at least some polyester fibre. Polyester-based clothing, on the other hand, will melt in high temperatures, whilst most natural fabrics will char. Molten fibres have the potential to cause permanent bodily harm.
Conclusion
Polymers are long-chain molecules whose properties are determined by their chain behaviour and chemical make-up or constitution. Polymer usage is on the rise, and the spectrum of general-purpose and specialty polymers has expanded dramatically in the last two decades.
