The water splits into an OH- and H+ group and they bond with either end of the now-split polymer, which will continue to occur rapidly until the polymer is broken down into monomers.

WebTo break a polyamide, we do the reverse - we add water. Adding water splits the polymer down the middle of the amide group, adding a hydrogen atom to the amine, and a hydroxyl group to the carboxylic acid. This leaves us with our monomers. In this case, we are left with 1,2-diaminoethane and benzene-1,4-dicarboxylic acid. WebPolymers are broken down into monomers in a process known as hydrolysis, which means “to split water.” ( Figure 3.3 ). During these reactions, the polymer is broken into two components: one part gains a hydrogen atom (H+) and the other gains a hydroxyl molecule (OH–) from a split water molecule.
