Oligomer vs. Polymer: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Oligomer is a molecule made of a few repeating units. Polymer is a larger molecule composed of many repeating units.
Key Differences
Oligomers are molecules consisting of a few monomer units, typically ranging from two to twenty. Polymers, in contrast, are large molecules composed of many repeating monomer units, often in the thousands.

The physical properties of oligomers differ significantly from polymers due to their size; oligomers are usually less complex and have lower molecular weights. Polymers, with their high molecular weight, exhibit unique properties like elasticity and plasticity.

Oligomers often serve as intermediates in the synthesis of polymers. In polymerization, monomers first form oligomers, which then link together to form long-chain polymers.

Chemically, oligomers may show distinct reactivity compared to polymers. The shorter chain length of oligomers can lead to different chemical behaviors, unlike polymers which have more uniform properties across their length.

Oligomer
A molecule composed of a small number of linked monomer units; a short polymer; - compounds called oligomers have less than one hundred monomer units and usually less than thirty. Oligomers of increasing length are called dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, decamer, etc. In colloquial laboratory jargon, they may also be referred to as nine-mer, ten-mer, eleven-mer, twelve-mer, etc., especially for oligomers of greater than eight units.
