There are two main kinds of polymers.
Type 1: Addition Polymers
Each small molecule adds to the end ofa growing chain. Polyethylene is an example
Type 2: Condensation Polymers
Monomer units come together with the eliminationof some small molecule (often water).Polyesters and nylons are examples

Condensation Polymers
Also called “Step-Growth Polymers”
Their synthesis does not involve a chainreaction.
Instead any two molecules can react atany time.

Instead any two molecules can react atany time.
Each end of the molecule reacts in turn forming dimers, trimers etc.
