OCR Salters Chemistry B F332 Advance Notice May 2011 Polymers on the move

i was wondering if anyone had any idea on any questions they may ask related to the advanced notice book it would help meee out very much :smile:
@hardeep29 I've got a list I hope it helps,
1. Define a polymer?
2. What's addition polymerisation?
3. Draw the monomer and the repeating unit of propene, ethene, PTFE, and PVC
4. Describe the attractive forces between Polymer chains in; polyethene and PVC
5. Properties of nylon and that hydrogen bonds can occur between the chains
6. Draw skeletal formula of polymers
7. what is natural rubber?
8. E/Z Isomerism
Lastly read storylines about Neoprene

And by the way could you tell me what the article actually is about?

Thanks, was this list of questions given by your chemistry teacher?

:frown:I strongly dislike polmers, especially drawing them :frown:

not liking this advance paper at all, hate polymers.

Anyone have any idea what could come up in general for the normal exam section?
- Drawing Monomers
- Different uses for different polymers, and how their structure affects it e.g Dipoles and Hydrogen bonds.
- Properties e.g. density and why say polychloroethane is more dense than polypropene.
- Radicals
- homolytic Fission
- Maybe something on combustion

Hope this helps :smile:
how about a "what is this used for and why?....." kind of thing
or is it too easy?

Draw the structure of poly(propene) and use it to explain why it is tough.

Draw the structure of poly(chloroethene) and use it to explain why it is strong.

Draw the full structure of the buta-1,3-diene monomer and the butadiene polymer repeating unit.

Define ‘elastomer’.

Suggest in terms of structure and reactivity why polyalkenes are ‘hard to bond’/can’t get chemical grab.

Explain and describe, in terms of intermolecular bonding, the difference in properties between thermoplastics and thermosets.

Draw the full structure of ethylene glycol.

Suggest the gases formed from burning foam.

Explain what ‘oil-based’ means.

What is meant by ‘a free radical’ and how do they form?

Using the reaction between chlorine and methane write equations to illustrate the meaning of the terms ‘initiation’, ‘propagation’ and ‘termination’
