Definition of polymer in English:



  • A substance which has a molecular structure built up chiefly or completely from a large number of similar units bonded together, e.g. many synthetic organic materials used as plastics and resins.

    • ‘High molecular weight polymers can have viscosity values in the millions of centipoise range.’
    • ‘The ability of living organisms to define the molecular composition of a polymer with complete accuracy is an enviable one.’
    • ‘Nucleic acids are also polymers, composed of repeating units called nucleotides.’
    • ‘Gels in the laboratory such as silica gel and some polymers have been studied and exploited for years.’
    • ‘This is usually dextrose, but amino acids and glucose polymers can also be used.’


Mid 19th century from German, from Greek polumeros ‘having many parts’, from polu- ‘many’ + meros ‘a share’.
