​1. Origin of Polymers

​Natural Polymers: polymers obtained by chemical processes inside the cells of organisms.

​Synthetic Polymers

​Man-made polymers produced by chemical reactions to form chemical bonds of monomers. many are the products of petroleum.

​Polymers made of one type of monomer are called homopolymers.

​2. Amount of monomers

​Polymers formed by more than one type of monomer is called copolymer.

​3. Structure and properties of a polymer.
