WebOct 16, 2024 · A concise lesson presentation (19 slides) which looks at meaning of the key term, polymers, and briefly explores addition and condensation polymers. The lesson begins with a fun exercise to enable students to come up with the word polymers so that they can be introduced to the definition and then relate this to another term, monomers. WebLipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources 1, 2 ^{1,2} 1, 2 start superscript, 1, comma, 2, end superscript. However, many other sources use the term “macromolecule” more loosely, as a general name for the four types of large biological molecules 3 , 4 ^{3,4} 3 , 4 start …

WebPolymer: Definition: It is a polymer with very weak intermolecular forces and Viscoelasticity. Thus, they are famously known as elastic polymers. Is a macromolecule or large molecule made up of clusters of subunits. Physical property: They inherit the unique property of elasticity. They inherit diverse properties based on the category. Morphology WebPoly (ethene) is a polymer made from a very large number of ethene molecules combined together. The C=C double bond in ethene is involved in the polymerisation reaction. It …
WebJan 16, 2024 · Elastomers are elastic materials with high flexibility and low strength molecular bonds (like rubber). Polymer fibers consist of polymer chains that have stronger molecular bonds than elastomers. Fibers are more rigid and less elastic than elastomers and can be composed of both natural and synthetic materials. Thermoplastics are more rigid … WebJan 13, 2024 · Amino acids like glutamic acid are examples of monomers. 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.
