28 Ιουλ 2023 · Synthetic polymers, also known as man-made polymers, are polymers that are artificially produced by humans. Polymers are composed of repetitive structural units called monomers. Polyethylene, a polymer renowned for its simplicity, is composed of ethene or ethylene monomer units.
A common name for many synthetic polymer materials is plastic, which comes from the Greek word "plastikos", suitable for molding or shaping. In the following illustrated example, many monomers called styrene are polymerized into a long chain polymer called polystyrene.
This chapter introduces synthetic polymers, emphasizing their significance in everyday life and various industries. It covers the fundamentals of polymer chemistry, including the methods of polymerization, types of polymers, and their applications.
5 ημέρες πριν · A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms and are the basis of many minerals and man-made materials.
5 ημέρες πριν · Synthetic polymers are produced in different types of reactions. Many simple hydrocarbons, such as ethylene and propylene, can be transformed into polymers by adding one monomer after another to the growing chain. Polyethylene, composed of repeating ethylene monomers, is an addition polymer.
Synthetic polymers are defined as polymers that are artificially produced in laboratories. These are also known as man-made polymers. Some of the examples of synthetic polymers are polyethylene (PE), polystyrene (PS), polyamides (nylon), poly (vinyl chloride) (PVC), synthetic rubber, teflon, epoxy, and several others [10].
