When does condensation polymerisation happen?

monomers of different functional groups to form bonds and give polymer chains where a small molecule is lost so atom economy is not 100%

2
New cards

What is the small molecule that is always eliminated in the natural condensation polymerisation?

water

3
New cards

How can you identify condensation polymers?

ester/amide link
