macromolecule (polymer molecule)

Also contains definitions of: macromolecular, polymeric
https://doi.org/10.1351/goldbook.M03667
A molecule of high @R05271@, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low @R05271@.
Notes:
  1. In many cases, especially for synthetic polymers, a molecule can be regarded as having a high @R05271@ if the addition or removal of one or a few of the units has a negligible effect on the molecular properties. This statement fails in the case of certain macromolecules for which the properties may be critically dependent on fine details of the molecular structure.
  2. If a part or the whole of the molecule has a high @R05271@ and essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low @R05271@, it may be described as either macromolecular or polymeric, or by polymer used adjectivally.
