Addition reactions are characteristic of monomers that contain either a double bond between two atoms or a ring of from three to seven atoms; examples include styrene, caprolactam (which forms nylon-6), and butadiene and acrylonitrile (which copolymerize to form nitrile rubber, or Buna N). Condensation polymerizations are typical of monomers containing two or more reactive atomic groupings; for example, a compound that is both an alcohol and an acid can undergo repetitive ester formation involving the alcohol group of each molecule with the acid group of the next, to form a long-chain polyester. In other words, groups of monomers are known as polymers. Thus molecules like ammonia, water, ethanol etc are not monomers. Monomers are building blocks of polymers. Glucose is an example of a monosaccharide. Each monomer may link in different ways to form a variety of polymers. Other surfactant molecules clump together into smaller aggregates called micelles, which also absorb monomer molecules. The prefix "poly-" means "many". Proteins being polymers are made up from repeating amide units and therefore named as polyamides. They can be used to prepare polymers with rigid, flexible, ionic, nonionic, hydrophobic, or hydrophilic properties.
