The table presents three monomer pairs that can polymerise. Complete the table by naming the polymerisation type for each pair.
$2$-aminopropanoic acid, $\text{CH}_3\text{CH(NH}_2)\text{CO}_2\text{H}$, is able to polymerise under suitable conditions. No other monomer takes part in this reaction. Draw a section of the polymer chain produced, including $\mathbf{three}$ monomer residues. Clearly indicate $\mathbf{one}$ repeat unit on your diagram.
$2$-aminopropanoic acid, $\text{CH}_3\text{CH(NH}_2)\text{CO}_2\text{H}$, occurs as two stereoisomers. Draw three-dimensional diagrams to illustrate the two stereoisomers of $2$-aminopropanoic acid. State the type of stereoisomerism shown.
The skeletal formula for compound $W$ is shown. When $W$ is combined with a second compound, known as a hardener, polymerisation takes place and a non-solvent-based adhesive is formed. Give the name of this type of non-solvent-based adhesive.
The hardener is a diamine. A diamine contains an alkyl chain with two amine groups that are not attached to the same carbon atom. Draw the structural formula of a compound that could act as a suitable hardener.
