Polymerisation

Question 1

Describe how other poly,ears can be made combining together other monomer molecules.

Answer 1

Poly(propene)
Poly(chloroethene)
Poly(tetrafluoroethene)

Question 2

Properties and uses of poly(ethene)

Answer 2

Flexible, cheap, good insulator

Plastic bag, plastic bottles, cling film, insulation for electrical wires

Question 3

Properties and uses of poly(propene)

Answer 3

Flexible, shatterproof, high softening point

Buckets and bowls

Question 4

Properties and uses of poly(chloroethene)

Answer 4

Tough, cheap, long lasting, good insulator

Window frames, gutters, pipes, insulation for electrical wires

Question 5

Properties and uses of poly(tetrafluoroethene)

Answer 5

Tough, slippery, resistant to corrosion, good insulator

Non- stick coatings for saucepans, bearings and skis, resistant to corrosive substances, stain proofing carpets, insulation for electrical wires

Question 6

What can happen in polymerisation?

Answer 6

Many ethene molecules can combine together in a polymerisation reaction.
The polymer formed is called poly(ethene)
