AS Chemistry - Polymers

HideShow resource information
Define biodegradable polymers
Break down naturally in the environment (using living organisms) into carbon dioxide and water
1 of 9
Which process makes polymers?
Addition polymerisation
2 of 9
What are always the monomers of polymers?
Alkenes
3 of 9
What are the advantages of polymers?
Make many useful household items, fairly unreactive, durable, do not break down naturally
4 of 9
What are the disadvantages of polymers?
Non biodegradable, releases toxic gases when burned
5 of 9
Outline separating and recycling
Use polymer identification codes to separate then recycle accordingly
6 of 9
outline using polymers as a fuel source
Burn (combust) the polymers under controlled conditions to produce heat energy. Toxic waste products (e.g. HCl) are removed using gas scrubbers for halogenated polymers.
7 of 9
Outline Feedstock recycling
Convert polymers into synthesis gas (hydrogen and carbon monoxide) and use as feedstock for conversion into useful products.
8 of 9
Outline developing biodegradable polymers.
Derived from renewable raw materials such as starch, maize and cellulose.
