the combining of several simpler molecules (monomers) to form a polymer.

po·lym·er·i·za·tion

(po-lim'ĕr-i-za'shŭn),
A reaction in which a high molecular weight product is produced by successive additions to or condensations of a simpler compound; for example, polystyrene may be produced from styrene, or rubber from isoprene, or a polynucleotide from mononucleotides, or microtubules from tubulin.

polymerization (pol´imər´izā´shən),

n the chaining together of similar molecules to form a compound of high molecular weight.
polymerization, addition,
n a compound formed by a combination of simple molecules without the formation of any new products; e.g., methylmethacrylate.
polymerization, condensation,
n the combination of simple, dissimilar molecules, with the formation of byproducts such as water or ammonia (e.g., vulcanite).
polymerization, cross,
n (cross linkage, cross-linked polymerization), the formation of chemical bonds between linear molecules, resulting in a three-dimensional network. Used for artificial teeth and denture bases because of superior craze resistance.
polymerization, cross-linked,
n See polymerization, cross.
polymerization, photo,
n a process in which a light source is used for polymerization.

Superabsorbent polymers can be produced using one of three primary methods: suspension polymerization, solution polymerization or gel polymerization.
Although norbornene monomers are polymerized with transition metal catalysts, polar groups deactivate these catalysts, making polymerization of monomers with polar groups impossible.
As new, stimuli-responsive "intelligent" polymers are developed, monitoring polymerization reactions for deviation from ideal cases and to gain more understanding of their underlying kinetics and mechanisms will become more and more important to successful production and process development, including use of energy and feedstocks, conservation of non-renewable resources and enhanced product quality and reliability.
