Polyhydroxyamide is a fire-resistant polyamide formed from the two monomers, F and G. Predict how many peaks will appear in the carbon-13 NMR spectra of F and G.
Draw the repeat unit of polyhydroxyamide. The amide bond must be displayed.
When poly(ethene) is made from ethene, several bonds are broken and formed. Put one tick (✓) in each row of the table to show the types of bonds broken and formed in this process.
Addition polymers can be sorted into two categories: homopolymer - a polymer made from the same monomer unit; copolymer - a polymer made from two or more different monomer units. The reaction of propene, $\text{CH}_3\text{CH}=\text{CH}_2$, with phenylethene, $\text{C}_6\text{H}_5\text{CH}=\text{CH}_2$, produces a copolymer. Draw a section of this copolymer chain that contains one molecule of each monomer.
Polyalkenes biodegrade very slowly. Explain why, with reference to the structures of the polymers.
Some polymers break down in the environment. Describe two processes by which this happens.
