condensation polymerisation

[Zahta]

how much do we need to know about condensation polymerisation  , because textbook has hardly  anything on it

[charmanderp]

It's just applied chemistry - more than two molecules join together, almost always via an oxygen molecule, to form a chain. The reaction includes the omission of a single compound, usually water.

The most common types that you'll come across will be acid-alcohol polymer, sugar-sugar polymers, DNA and polypeptides.

Also the molecules need 2 functional groups at the ends!

And unlike addition polymers, condensation polymers are biodegradable. The reverse reaction is known as hydration, which involves the addition of water in conjunction with a catalyst (H+ in the form of an acid or an enzyme).

Hydrolysis?

Ah woops. I always tell my Chemistry teacher off for mixing them up, and now I've done it ):

then what's hydration? Is it when water molecules disassociate and surround ions/polar substances? Not sure.

[charmanderp]

Hydration is the addition reaction between an unsaturated hydrocarbon (an alkene) and water, in the presence of a catalyst, to produce an alcohol.
