Polymer
A long molecule consisting of many similar or identical monomers linked together.
A polymer is a large molecule made up of repeating units called monomers. These monomers are chemically bonded together to form a long chain or network structure. The word “polymer” is derived from the Greek words “poly” meaning “many” and “meros” meaning “parts”.
Polymers can be natural or synthetic. Examples of natural polymers include proteins, DNA, and cellulose. Synthetic polymers include plastics, synthetic fibers, and rubbers.
Polymerization is the process of forming a polymer from monomers. There are two main types of polymerization: addition polymerization and condensation polymerization. In addition polymerization, monomers with double bonds react with each other to form a chain. In condensation polymerization, monomers with reactive functional groups react with each other, producing a small molecule (such as water) as a byproduct.
Polymers have many applications in various industries such as packaging, textiles, electronics, and biomedical engineering. They are also used in everyday products like plastics, adhesives, and coatings. The properties of polymers can be tailored by varying the monomer structure, molecular weight, and processing conditions.
