Synthetic and Naturally occurring polymers-PAPER2

Question 1

What is addition polymerisation?

Answer 1

Takes place when a molecule gets added across the double bond of another, (the double bond opens up and is replaced by another molecule.)

Question 2

What is condensation polymerisation?

Answer 2

Monomers reacting together to form the polymer and sometimes a small molecule such as water.

Question 3

What are the differences between condensation and addition polymerisation?

Answer 3

Addition- all the monomers contain a carbon to carbon double bond (unsaturated). The only product of the reaction is the polymer unlike condensation
Condensation- Monomers can be saturated and contain no carbon to carbon double bond. As well as the polymer a small molecule such as water or hydrogen chloride is also formed.
