A molecule of intermediate relative molecular mass
, the structure of which essentially comprises a small plurality of units derived, actually or conceptually, from molecules of lower relative molecular mass
A molecule is regarded as having an intermediate relative molecular mass if it has properties which do vary significantly with the removal of one or a few of the units.
If a part or the whole of the molecule has an intermediate relative molecular mass and essentially comprises a small plurality of units derived, actually or conceptually, from molecules of lower relative molecular mass, it may be described as oligomeric, or by oligomer used adjectivally.
