Polymer is coined from to Greek word “poly” means many
“mer” means parts.
Defination: polymer is defined as very large molecules
having high molecular mass which are formed by joining
of repeating structural unit on large scale.
Monomer : repeating structural unit derived from some
simple and reactive moleculeles are linked to each other
by covalent bond.
Polymerization : process of polymer formation.
