In polymerization of ethene why the phenyl radical affect the double bond of ethene and in chlorination by chorine radical it does not affect double bond ??

When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.This unit provides an overview of the main types of polymers characterised by how they are made, how their structures govern their general properties and how these properties can be refined by their formulation using a range of additives. Finally the unit summarises the range of processing techniques that can be used to convert polymers into a vast range of different products.Each of the other units in the Polymers section describes the manufacture, properties and uses of an individual polymer or group of polymers in more detail.
