A) Draw Two chains (representing at least 2 monomers each) of PVA with borax between them crosslinking them: B.) Two repeat units of nylon as a polymer c) what do the two numbers correspond to in the name "Nylon-66?" what would the chemical structure of the repeat unit be in "Nylon-2,2"? (use ChemDraw)
Question C1. Give two (2) ways in which you can increase the yield strength of a metal and briefly explain how each works to increase the yield stress. Question C2. An aluminium-Silicon casting alloy has a composition that is close to the Al-Si eutectic composition. Give two reasons why this composition is used to cast aluminium based engine blocks Question C3. Describe briefly three (3) mechanisms by which short randomly aligned fibres add to the toughness of a composite. can...
The repeat unit of a polymer is the smallest section of
the polymer that includes all of the original monomers and is
identically repeated end to end along the entire polymer chain.
Draw the repeat unit of the polymer that results via a
condensation reaction, as shown in Intro figure 2, between
the diacid and the diamine shown below.
To indicate that the polymer repeats, leave the atom at each end
of the repeat unit with one less bond. For...
