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.
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.
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.
Synthetic polymers are polymers that are synthesized or modified in the laboratory. One of the advantages of synthetic polymers over natural polymers is that synthetic polymers are usually recommended in most research due to their high purity and reproducibility.
Polymers consist of many repeating monomer units in long chains, sometimes with branching or cross-linking between the chains. A polymer is analogous to a necklace made from many small beads (monomers). A chemical reaction forming polymers from monomers is called polymerization, of which there are many types.
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].
