What are biodegradable polymers?

Break down naturally in the environment using living organisms into carbon dioxide and water.

2 of 7

How are monomers joined together?

Polymerisation.

3 of 7

What are advantages of polymers?

1)Make useful household items.2)Fairly unreactive.3)Durable.4)Don't break down naturally.

4 of 7

What are disadvantages of polymers?

1)Non biodegradable.2)Release toxic gases when burned.

5 of 7

How are chemists trying to solve these problems?

1)Separation and recycling- use identification codes.2)Fuel source-burn polymers, toxins removed by gas scrubbers.3)Feedstock recycling-convert synthesis gas and use as feedstock to convert to useful products.4)Develop biodegradable polymers.
