Definition of polymer in English:

polymer

noun ˈpɒlɪməˈpɑləmər

Chemistry

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.
〔化〕聚合物
Example sentencesExamples
- This is usually dextrose, but amino acids and glucose polymers can also be used.
- 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.
- Gels in the laboratory such as silica gel and some polymers have been studied and exploited for years.
- Nucleic acids are also polymers, composed of repeating units called nucleotides.

Derivatives

polymeric

adjective pɒlɪˈmɛrɪkˌpɑliˈmɛrɪk

Chemistry

The oil droplets contain a molecular metal oxide precursor, which polymerises on contact with water forming a polymeric metal oxide coating at the oil-water interface.
Example sentencesExamples
- Quill has already identified several ionic liquids in which a wide range of inorganic, organic and polymeric materials are highly soluble, making them prime candidates for small reactor volumes.
- Polyphosphates are a group of phosphates that are created from polymeric chemical compounds.
- So, it seems, the Earth's primordial soup was primed with the monomers for making the polymeric components of primitive life.
- Latex emulsions are made up of polymeric materials suspended in an aqueous solvent by a surfactant.
