Question

What is the difference between oligomerization and polymerization?

ANSWER

Differences between Oligomerization and Polymerization

Oligomerization Polymerization
Process The process of converting a monomer or a mixture of monomers into oligomers (Zhou, 2013). Transition of low molecular weight constitutes (monomers) into high molecular weight constitutes (polymers) via a chemical reaction (Zhou, 2013).
Substances involved Oligomer: A substance composed of molecules containing a few of one or more species of atoms or groups of atoms (constitutional units) repetitively linked to each other. The physical properties of oligomers vary with the addition or removal of one or a few of the constitutional units from its molecules (Zhou, 2013). Polymer: A substance composed of molecules characterized by the multiple repetition of one or more species of atoms or groups of atoms linked to each other in amounts sufficient to provide a set of properties that do not vary markedly with the addition or removal of one or a few of the constitutional units (Zhou, 2013).
Physical Property Varies with the addition or removal of one or a few of the constitutional units from its molecules. Does not vary markedly with the addition or removal of one or a few of the constitutional units.
Examples
  • Protein Oligomerization.
  • DHA and RNA Oligomerization reactions (Rana, 2011).
  • Collagen triple helix and the α-helical coiled-coil (Adams & Engel, 2007).
  • Alkene Polymerization.
  • Free-radical Polymerization of Styrene.
  • Epicatechin Polymerization.
