polymer definitions

WordNet (r) 3.0 (2005)

n
1: a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers

Merriam Webster's

noun Etymology: International Scientific Vocabulary, back-formation from polymeric, from Greek polymer?s having many parts, from poly- + meros part more at merit Date: 1866 a chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units polymeric adjective polymerism noun

Britannica Concise

Any of a class of natural or synthetic substances composed of macromolecules that are multiples of monomers. The monomers need not all be the same or have the same structure. Polymers may consist of long chains of unbranched or branched monomers or may be cross-linked networks of monomers in two or three dimensions. Their backbones may be flexible or rigid. Inorganic polymers can be elements or compounds, incl. diamond, graphite, feldspar, and glass. Many important natural materials are organic polymers, incl. cellulose (from sugar monomers), lignin, rubber, proteins (from amino acids), and nucleic acids (from nucleotides). Synthetic organic polymers include many plastics, incl. polyethylene, the nylons, polyurethanes, polyesters, vinyls (e.g., PVC), and synthetic rubbers. The silicones, with an inorganic backbone of silicon and oxygen atoms and organic side groups, are the most important mixed organic-inorganic compounds.

Oxford Reference Dictionary

n. a compound composed of one or more large molecules that are formed from repeated units of smaller molecules. Derivatives: polymeric adj. polymerism n. polymerize v.intr. & tr. (also -ise). polymerization n. Etymology: G f. Gk polumeros having many parts (as POLY-(1), meros share)

Webster's 1913 Dictionary

Polymer Pol"y*mer, n. [See Polymeric.] (Chem.) Any one of two or more substances related to each other by polymerism; specifically, a substance produced from another substance by chemical polymerization. [Formerly also written polymere.]

Collin's Cobuild Dictionary

(polymers) A polymer is a chemical compound with large molecules made of many smaller molecules of the same kind. Some polymers exist naturally and others are produced in laboratories and factories. N-COUNT
