C11.2 Condensation Polymerisation Flashcards
What is condensation polymerisation?
Small molecule is formed as a by-product each time a bond is formed between two monomers
What is the main difference between condensation polymerisation and addition polymerisation?
In addition there is only one product formed
In condensation there are 2 different products
What happens in condensation polymerisation?
The condensation polymer + a small molecule is formed
Most commonly either H20 or HCL
What type of monomers are used in condensation polymerisation?
2 different monomers
One monomer will have a certain functional group at both ends of its molecule
Other monomer will have a different functional group as its ends
How are long polymer chains formed?
When functional groups on the 2 different monomers react
How are polyesters formed?
From the condensation polymerisation of a diol and a dicarboxylic acid with H2O given off in the reaction
Why are fumes given off when nylon is made?
As the 2 different monomers react together to form nylon also give a small molecule off which is HCL gas
