Difference between addition polymerization and condensation polymerization



Addition polymerization
Condensation polymerization
The addition polymerization means that 
two monomers react with each other and 
no other small molecules are generated. 
The best example is polymerization of 
ethylene.
The condensation polymerization, as a 
contrast, normally involves the generation 
of small molecule products.
It requires two like molecules.
It requires two unlike molecules.
Kinetic long linear chain reaction.
Intermolecular reaction.
Very fast reaction 10-2 – 10-6sec
Slow reaction takes hours and days to 
complete.
No by total.
By product it produced.
Polymer produced thermoplastic.
Chemo setting plastic produced.
Example: PVC, Teflon, Poly ethylene.
Example: Bakelite, Silicon, GRP, Polystyrene
