A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins. Monomers bind to other monomers to form repeating chain molecules through a process known as polymerization. Monomers may be either natural or synthetic in origin.
WebSep 7, 2024 · Polymer Chemistry: Crystallization Tendency. David Whisnant. Wofford College. The most common way of classifying polymers is to separate them into three groups - thermoplastics, thermosets, and elastomers. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous. WebChemistry. Natural Polymers: Examples & Uses. Prev Article Next Article . The word “polymer” comes from the Greek words “poly,” which means many, and “meros,” which means parts or units. Each polymer molecule consists of a long chain of repetitive structural units, called monomers, linked together via covalent bonds.
