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
