Polymers are widely used in modern society due to their versatile properties.
However, the disposal of these polymers after their useful lifetime presents significant environmental challenges. The uses of specific polymers are directly related to their physical and chemical properties.
Table 1 outlines the uses of three common polymers.
| Polymer | Common Uses |
|---|---|
| Low-density poly(ethene) (LDPE) | Carrier bags, flexible squeeze bottles |
| Poly(chloroethene) (PVC) | Window frames, underground drainage pipes, electrical wire sheathing |
| Poly(tetrafluoroethene) (PTFE) | Non-stick frying pan coatings, chemical-resistant gaskets |
Discuss the relationship between the molecular structure/properties of these three polymers and their uses as shown in Table 1, and evaluate the environmental problems specifically associated with their disposal.
