Condensation Polymerization

WHAT IS CONDENSATION POLYMERIZATION

condensation polymerization

Condensation polymers are any kind of polymers formed through a condensation reaction where molecules join together–losing small molecules as by-products such as water or methanol.

EXAMPLE – CONVERTING ETHYLENE TEREPHTHALATE TO POLYETHYLENE

CONDENSATION POLYMERIZATION

STEP 1: DRAW TWO DIFFERENT MONOMER MOLECULAR STRUCTURE
MOLECULE A AND MOLECULE B

Condensation Polymerization - Making Plyesters or PET

ester-linkageThis pretty symbol you see is called an ester linkage formed by combining acid and an alcohol. You don’t have to worry about it, Ā just draw it in šŸ™‚

STEP 2: COMBINE THE MONOMERS AND REMOVEĀ THE WATER MOLECULE
THE COMBINATION PRODUCES A WATER MOLECULE

STEP 3: STRING THE MOLECULES TOGETHER WITHOUT THE WATER
Make a continuous string of molecules, below shows an example of 2 molecules linked together.

STEP 4: MAKE POLYMER WITH NTH TERM
You can join lots of molecules together and keep repeating the structure.
