The polymer chains will trimerise under these conditions, forming a stable trimer that resists further addition reactions.

When the protein concentration increases, the enzyme trimerises and loses its activity.

During the synthesis, the intermediate monomers trimerised unexpectedly, altering the product distribution.

The polymer chains were trimerising on the surface, gradually changing the material's optical properties.

The trimerisation of the reactive intermediate was confirmed by NMR and mass spectrometry.

The chemists reported several unexpected trimerisations during the solvent-free synthesis, which complicated the purification process.
