A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics … See more Polymers are of two types: naturally occurring and synthetic or man made. Natural Natural polymeric materials such as hemp, shellac, amber, wool, silk, and natural rubber have been used for … See more Polymer properties depend of their structure and they are divided into classes according to their physical bases. Many physical and … See more There are multiple conventions for naming polymer substances. Many commonly used polymers, such as those found in consumer products, … See more Polymer characterization spans many techniques for determining the chemical composition, molecular weight distribution, and physical properties. Select common … See more Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During … See more The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. There is in fact a hierarchy of … See more Nowadays, synthetic polymers are used in almost all walks of life. Modern society would look very different without them. The spreading of polymer use is connected to their … See more WebNylon is a generic designation for a family of synthetic polymers composed of polyamides (repeating units linked by amide links). Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes.: 2 Nylon polymers can be mixed with a wide variety of additives to achieve many property variations.
