Addition Polymerization
|
Condensation Polymerization
|
1. 1. Only
olefin compounds can undergo addition polymerization.
2. Polymerization
proceeds through self-addition of monomers.
3.
There is absolutely no elimination of any
by products.
4. The
polymer chain is build up very rapidly (free radical chain reaction).
5. The
addition polymerization is brought about by free radicals, ionic or
co-ordination mechanism.
6. Linear
polymers are produced.
7. The
polymer produced has the same elemental composition as that of the monomer.
8. The
molecular weight of polymer is an integral multiple of that of the monomer.

The
monomers having two or more reactive functional groups can undergo
condensation polymerization.
2. Polymerization proceeds through
intermolecular condensation.
3. There is continuous elimination of byproducts.
4. The polymer chain build up is slow and
step wise.
5. Polymerization is catalyzed by acids or
alkali.
6. Linear or cross linked polymers are
produced.
7. The elemental composition of the polymer
is generally different from that of its monomers.
8. The molecular weight of polymer is not an
integral multiple of that of the monomer.

Chemistry of Synthetic Polymers
In this blog you can get the Chemistry and Applications of some synthetic polymers. Wonder plastic Teflon is discussed with its Chemistry and applications. I have written about the Chemistry and importance of polymer composites.
