Topic 1 (production): DP 1:(4) identify that ethylene serves as a monomer from which polymers are made Flashcards
1
Q
What is a monomer?
A
A single molecule (such as ethylene) that when added form polymers
2
Q
What is a polymer?
A
The result of the addition of many monomers to form very long chains of monomers (which form new
substances which specific qualities and uses for everyday life).
3
Q
What is polymerisation?
A
The reaction of monomers to form a polymer.
4
Q
Why is ethylene able to undergo polymerisation?
A
- Because of the high reactivity of its double bond.
- Ethylene becomes polyethylene
5
Q
What are some examples of some products which ethylene is used as a production starting point of?
A
- insecticides
- refrigerants
- explosives
- pharmaceuticals
6
Q
What are some exaples of polymers other than polyethylene?
A
- Starch: made up of many glucose molecules
- Proteins: polymers of amino acids
- DNA: polymer of nucleotides
