Word Origin and History for polymer
Online Etymology Dictionary, © 2010 Douglas Harper
- Any of numerous compounds of usually high molecular weight and consisting of up to millions of repeated linked units, each a relatively light and simple molecule.
The American Heritage® Stedman's Medical Dictionary Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. Published by Houghton Mifflin Company.
- Any of various chemical compounds made of smaller, identical molecules (called monomers) linked together. Some polymers, like cellulose, occur naturally, while others, like nylon, are artificial. Polymers have extremely high molecular weights, make up many of the tissues of organisms, and have extremely varied and versatile uses in industry, such as in making plastics, concrete, glass, and rubber.♦ The process by which molecules are linked together to form polymers is called polymerization (pŏl′ə-lĭm′ər-ĭ-zā′shən).
