polymerization

 [pah-lim″er-ĭ-za´shun]
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

[pə·lim′ər·i·zā′shən]
the act or process of forming a compound (polymer), usually of high molecular weight, by the combination of simpler molecules (monomers).

po·lym·er·i·za·tion

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.
