Answer
One problem with recycling polymers is that they need to be sorted into different types. Many polymers cannot easily be separated from each other, making it time-consuming and expensive to process them for recycling.
Step 2
Describe a problem associated with the disposal of polymers.

Answer
Polymers can persist in landfills for very long periods, as they do not biodegrade easily. Additionally, their combustion can produce toxic gases, which can be harmful to the environment.

Answer
The structure of a poly(chloroethene) molecule with three repeating units can be represented as follows:
H H H

---C---C---C---
| | |
Cl Cl Cl
This shows the carbon backbone with chlorine substituents.
