WebFeb 12, 2024 · Monomer Definition. A monomer is a small molecule that reacts with a similar molecule to form a larger molecule. It is the smallest unit in a polymer, which is often a macromolecule with high molecular weight. Monomers are the building blocks for biological macromolecules such as DNA, RNA, proteins and carbohydrates. WebPolymers provide a readily available, cheap alternative to many metal, glass, paper and cardboard materials in everyday use; The low reactivity of many polymers makes them ideal for certain uses, e.g. food packaging, but at the same time creates problems with their disposal as a lot of polymers are non-biodegradable. There are many published articles … WebThere are two methods by which polymers are made: Addition polymerisation. Condensation polymerisation. In addition polymerisation, alkenes add to themselves. As this addition proceeds further a long molecular chain is formed. The alkene is the repeating unit in the chain (the monomer). The chain itself is the polymer. scion tc 05 brake pads
