2. Chemical aging in the presence of water. Hydrolysis

2.1 Hydrolysis reaction

It can be summarized as follows: XY+ H2OXOH+HY

The — X — Y — group may be lateral [e.g. ester in polyvinyl acetate or acrylic and methacrylic polymers], but this is relatively uncommon in the field of industrial materials ageing.

It can be found in the macromolecule's skeleton, and in this case (the most common), hydrolysis leads to a break in the skeleton, resulting in the eventual loss...
