| A polymer is classified as a condensation polymer if its synthesis involves the elimination of small molecules, or it contains funtional groups as part of the polymer chain, or its repeating unit lacks certain atoms that are present in the monomer to which it can be degraded. If a polymer does not fulfill any of these requirements, it is classified as an addition polymer. |
