Question 0

What is meant by a condensation polymer?

Answer 0

A polymer that produces EXTRA molecules (usually water) when its monomers combine

Question 1

Why is there a need for alternative sources of compounds presently obtained from the petrochemical industry

Answer 1

Crude oil is a fossil fuel and hence, not a renewable resource

Question 2

Describe the reaction involved when a condensation polymer is formed

Answer 2

• The functional groups of the two monomers react together, forming a new bond and water

Question 3

Describe the structure of cellulose

Answer 3

• Cellulose is a naturally occurring condensation polymer (biopolymer)
• It is a very linear molecule due to its straight chains

Question 4

Discuss the potential of cellulose as a raw material

Answer 4

• Although cellulose can provide limitless amounts of renewable raw materials, it is currently too expensive due to the process required to derive ethylene from it
• Therefore it has a great potential but is currently not economical
