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 chemical properties describe how a polymer behaves as a continuous macroscopic material. They are classified as bulk properties, or 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 … See more Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some … 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 … See more Polymer characterization spans many techniques for determining the chemical composition, molecular weight distribution, and physical properties. Select common techniques include the following: • See more WebPolymers is a peer-reviewed, open access journal of polymer science published semimonthly online by MDPI. ...
