polymer

/poly·mer/ (pol´ĭ-mer) a compound, usually of high molecular weight, formed by the combination of simpler molecules (monomers); it may be formed without formation of any other product (addition p.) or with simultaneous elimination of water or other simple compound (condensation p.) .

The polymer cellulose consists of linked repeating units of the monomer β-d-glucose.

polymer

[pol′imər]
Etymology: Gk, polys + meros, part
a compound formed by combining or linking a number of monomers, or small molecules. A polymer may be composed of many units of more than one type of monomer (a copolymer) or of many units of the same monomer (a homopolymer).

polymer

A chain molecule made up of repetitions of smaller chemical units or molecules called monomers. Polysaccharides, for instance, are long chains made up of repeated units of simpler monosaccharide sugars. Proteins are polymers of AMINO ACIDS. Polymerization is the process of causing many similar or identical small chemical groups to link up to form a long chain. From Greek, poly , many and meros , a part.

polymer

a compound of high molecular weight formed of long chains of repeating units (MONOMERS).

Polymer

A substance formed by joining smaller molecules. For example, plastic, acrylic, cellulose acetate, cellulose propionate, nylon, etc.

polymer

high-molecular-weight compound; formed as a chain of repeated base units

polymer (pˑ·l·mer),

n compound that comprises several repeating units of monomers. See also monomer.
