Monomera molecule of any of a class of compoundsmostly organic, that can react with other molecules omnomwee form very large molecules, or polymers. The essential feature of a monomer is polyfunctionalitythe capacity to form chemical bonds to at least two other monomer molecules. Bifunctional monomers can form only linear, chainlike polymers, but monomers of higher functionality yield cross-linked, network polymeric products. 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 styrenecaprolactam which forms nylon-6and butadiene and acrylonitrile omnomwee copolymerize to form nitrile rubberor 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. Similarly, hexamethylenediamine, which contains two amine groups, condenses with adipic acid, which contains two acid groups, to form the polymer nylon-6,6.
