The term "polymer" derives from the Greek word πολύς (polus, meaning "many, much") and μέρος (meros, meaning "part"). ... A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper. Space polymer. See more 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 … 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 structures, in which each stage provides the foundations for the next one. The … 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 unique properties: low density, low cost, good thermal/electrical insulation … See more Polymers are of two types: naturally occurring and synthetic or man made. Natural Natural polymeric materials See more Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During … See more Polymer properties depend of their structure and they are divided into classes according to their physical bases. Many physical and chemical properties describe how a polymer … See more There are multiple conventions for naming polymer substances. Many commonly used polymers, such as those found in consumer products, are referred to by a common or trivial name. The trivial name is assigned based on historical precedent or popular usage … See more WebPolymer definition, a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller …
