States of matter — practice question

Methyl 2-cyanoprop-2-enoate, $W$, is the principal ingredient in Super Glue, a fast-setting adhesive. When the adhesive hardens, monomer $W$ undergoes polymerisation.
(a(i))[2]

Draw a part of the polymer that contains two repeat units.

(a(ii))[1]

Name the polymerisation type taking place.

(a(iii))[2]

Suggest two kinds of intermolecular force that could exist between the Super Glue polymer and the items being glued together. For each one, refer to the atoms/groups in the Super Glue polymer taking part in the interaction.

(b(i))[2]

$W$ can be made in three stages, beginning with 2-oxopropanoic acid, $X$. Suggest the identities of compounds $Y$ and $Z$ by drawing their structures in the boxes.

(b(ii))[4]

Suggest appropriate reagents and conditions for each of steps 1-3.
