The table shows three pairs of monomers that are capable of polymerisation. Complete the table by identifying each type of polymerisation.

1. (a)pair of monomers HOCH₂CH₂OH and HO₂CCH₂CO₂H and HO OH Cl Cl CH₃CHCF₂ and CH₃CHCH₂ type of polymerisation[1]
2. (b)(i)2-aminopropanoic acid, CH₃CH(NH₂)CO₂H, can polymerise under suitable conditions. No other monomer is involved in this reaction. Draw a section of the polymer chain formed including three monomer residues. Clearly identify one repeat unit on your diagram.[3]
3. (b)(ii)2-aminopropanoic acid, CH₃CH(NH₂)CO₂H, exists as two stereoisomers. Draw three-dimensional diagrams to show the two stereoisomers of 2-aminopropanoic acid. State the type of stereoisomerism shown. type of stereoisomerism[2]
4. (c)(i)The skeletal formula of compound W is shown. [Figure X.X] When W is mixed with a second compound, called a hardener, a polymerisation reaction occurs, producing a non-solvent-based adhesive. Give the name of this type of non-solvent-based adhesive.[1]
5. (c)(ii)The hardener is a diamine. A diamine has an alkyl chain with two amine groups which are not bonded to the same carbon atom. Draw the structural formula of a compound that would make a suitable hardener.[1]
