Short Note

How are polythene and neoprene prepared?

#### Solution

The antibiotic which is effective against a wide range of gram positive and gram negative bacteria known as broad spectrum antibiotic.
Preparating polyethene : The monomer used is ethene. It is an addition polymer. It is of two types.
$\ce{n CH2 = CH2 ->[Δ] [-CH2 - CH2-]_n}$

Preparating of Neoprne : The monomer used is chloroprene (2-chlorobuta-1,3-diene). It is superior to natural rubber and resistant to chemical action. It is used in the manufacture of chemical containers , conveyor belts, gaskets etc.

Concept: Types of Polymerisation Reactions - Addition Polymerisation Or Chain Growth Polymerisation
