Monomer

A monomer (/ˈmɒnəmər/ MON-ə-mər; mono-, "one" + -mer, "part") is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.

For example, the formation of many nylons requires equal amounts of a dicarboxylic acid and diamine.

For example, small amounts of 1-octene monomer are copolymerized with ethylene to give specialized polyethylene.

For polynucleic acids (DNA/RNA), the monomers are nucleotides, each of which is made of a pentose sugar, a nitrogenous base and a phosphate group.

The most abundant natural monomer is glucose, which is linked by glycosidic bonds into the polymers cellulose, starch, and glycogen.

This nylon is formed by condensation polymerization of two monomers, yielding water
