Explain Unsaturated Compound
|
An unsaturated compound is a compound which is able to break the double bond and add on extra atoms to the loecule in an addition reaction
|
|
|
Explain Addition Reaction
|
An addition reaction is when
|
|
|
Explain addition polymer
|
An addition polymer is when multiple monomers add together
|
|
|
Polymerization
|
Polymerization is when many monmers form to make a polymer.
|
|
|
Are polymers saturated or unsaturated
|
Saturated
|
|
|
Should polymers be reactive or unreactive
|
Polymers should be reactive because they are saturated.
|
|
|
Give the modern and more common name for propene (propylene)
|
Polypropylene, PP
|
|
|
Give the modern and more common name for phenyethene (styrene)
|
Polystyrene, PS
|
|
|
Give the modern and more common name for tetrafluoroethene
|
Teflon, PTFE
|
|
|
Why are addition polymers non-biodegradable?
|
They are non-biodegradable as they are all single bonds
|
|
|
What problems are associated with addition polymers being non-biodegradable
|
It leads to them not decomposing
|
|
|
Explian the difference between thermosofting and thermosetting polymers
|
Thermosetting polymers can only be heated and molded once but thermosoftening plastics can be used more than once.
|
|
|
Give an example of a termosoftening polymer
|
Melamine
|
|
|
Give an example of a thermosetting polymer
|
Bakerlite
|
|
|
What are the problems associated with the disposal and recycling of plastic waste
|
It will not rot or degrade if buried.
It gives off poisonous fumes (hydrogen chloride, hydrogen cyanide) if burnt. Plastics must be recycled separately according to each type. |
