Polymers of Commercial Importance
- Polypropene is formed by the repetitive joining of propene. Propene is the monomer of Polypropene. It is used in the preparation of different materials like fibres, ropes, pipes etc.
- Polystyrene is formed from aromatic hydrocarbons, styrene is its monomer. It is used as a wrapping material to provide coverage to important materials, cabinets of television, in making radios.
- Polyvinyl Chloride (PVC) is formed by combining a large number of molecules of vinyl chloride. Vinyl chloride is its monomer. It is used in making raincoats and especially in water pipes.
- Glyptal is a synthetic polymer that is formed by monomers of Ethylene glycol and Phthalic acid. It is used in the manufacturing of paints, fabrics, lacquers etc.
- Bakelite is known as Polyoxybenzylmethylenglycolanhydride. Phenol and Formaldehyde are used as monomers to produce bakelite which is formed by the condensation reaction of these monomers.
- Natural Rubber is composed of polyisoprene molecules linked together to form an elastomeric structure. Natural rubber is used for various purposes like making tyres, rubber bands, lid grippers etc.
- Polypropylene is a hydrocarbon polymer that has a linear structure. It is a multifaceted polymer as it has properties of plastic as well as fibre and hence is used for multi-purposes. Propylene is the monomer of polypropylene.
- Polyethylene Terephthalate also termed PET is a thermoplastic polymer. Ethylene glycol and terephthalic acid are used in the preparation of Polyethylene Terephthalate and in making different things like containers for packing food and drinks.
