pol·y·mer

 (pŏl′ə-mər)
n.
Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule.

[Greek polumerēs, consisting of many parts : polu-, poly- + meros, part; see (s)mer- in Indo-European roots.]

polymer

(ˈpɒlɪmə) or

polymeride

n
(Elements & Compounds) a naturally occurring or synthetic compound, such as starch or Perspex, that has large molecules made up of many relatively simple repeated units. Compare copolymer, oligomer
polymerism n

pol•y•mer

(ˈpɒl ə mər)

n.
a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon.
[1865–70; < Greek polymerḗs having many parts. See poly-, -mer]

pol·y·mer

(pŏl′ə-mər)
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 are used to make such materials as plastics, concrete, glass, and rubber. ♦ The process by which molecules are linked together to form polymers is called polymerization (pə-lĭm′ər-ĭ-zā′shən).

polymer

A material containing very large molecules which are built up from a series of small basic units (monomers). There can be between hundreds and hundreds of thousands of basic units in a polymer.
