Answer to Question #162975 in Physics for Ajay

Question

Describe the different types of polymerization processes with an example of each.

Answer 1

 Broadly polymerization can be classified into two categories,

Step-Growth or Condensation Polymerization

Chain-Growth or Addition Polymerization

Addition Polymerization

As the name suggests addition polymers form when an addition reaction occurs. The repeating monomers form a linear or branch structure depending on the type of monomer. During addition polymerization, the monomers rearrange themselves to form a new structure. But there is no loss of an atom or a molecule.

Condensation Polymerization

Condensation polymers form from the step growth polymerization. Here when molecules of monomers react to form a bond they replace certain molecules. These molecules are the by-product of the reaction. In most cases, this by-product is a water molecule.
