Usually conferred by acrylic and methacrylic esters which have been substituted with an hydroxyl group. Examples of common hydroxyl substituted monomers are:

(i) Carboxyl Functionality

Acrylic and methacrylic acid are most commonly used to introduce carboxyl functionality into a polymer.

(ii) Epoxy Functionality

Glycidyl acrylates and methacrylate are generally used to introduce epoxy groups into the polymer

Glycidyl Methacrylate

Glycidyl acrylate is volatile and toxic and finds limited use. Glycidyl methacrylate is much less hazardous and is normally used in preference. Suppliers of these monomers are difficult to obtain outside Japan.
