Natural polymers are polymers that are produced by living organisms, such as plants and animals. Some examples of natural polymers include cellulose, which is found in plant cell walls, and silk, which is produced by silkworms. Natural polymers are often biodegradable, which means that they can be broken down by microorganisms in the environment.
Synthetic polymers are polymers that are man-made, rather than being produced by living organisms. Some examples of synthetic polymers include polyethylene, which is used to make plastic bags, and nylon, which is used to make clothing. Synthetic polymers are often not biodegradable, which means that they can accumulate in the environment and cause pollution.
Here is a table summarizing the key differences between natural and synthetic polymers:
| Feature | Natural polymers | Synthetic polymers |
|---|---|---|
| Source | Produced by living organisms | Man-made |
| Biodegradability | Often biodegradable | Often not biodegradable |
| Examples | Cellulose, silk | Polyethylene, nylon |
