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 should be displayed in full.
When poly(ethene) is made from ethene, many bonds are broken and formed. Place one tick (✓) in each row of the table to show the bond types broken and formed in this process.
Addition polymers may be grouped into two types. Homopolymer - a polymer consisting of the same monomer unit. Copolymer - a polymer consisting of 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 length of the chain of this copolymer that includes one molecule of each monomer.
Polyalkenes biodegrade very slowly. Explain why, using the structures of the polymers as your reference.
Some polymers degrade in the environment. Describe two processes by which this happens.
