Chapter 9, Problem 13Q

Interpretation Introduction

Interpretation:

The polymerization of butadiene to synthetic rubber has to be identified that whether it is addition or condensation polymerization.

Concept Introduction:

Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.

Monomer: A molecule is considered as monomer when this molecule bonds with another identical molecule which results to form polymer.

Based on the techniques involved in preparation of polymers, it can be classified as addition polymer and condensation polymer.

Addition polymer is formed when the monomers undergoes addition reaction. These polymers are formed when the bonds in monomers undergoes rearrangement without loss of atom/molecule. This addition reaction takes place under pressure, heat or in presence of some catalyst.

Condensation polymer is formed when the monomers with two different functional groups undergoes reaction where the bond in monomer undergoes rearrangement with elimination of small molecules present.
