Q.Define the term polymerisation.

Polymerisation is defined as the chemical process by which a large number of relatively small monomer molecules combine together, through repeated formation of covalent bonds, to produce a single large molecule of high molecular mass called a polymer.

Polymerisation can proceed by two broad mechanisms:

• Addition polymerisation: monomers with a reactive double/triple bond add to one another with no loss of atoms (e.g., $n\,CH_2=CH_2 \rightarrow -[-CH_2-CH_2-]_n-$). …

State the general definition first, then briefly note the two mechanistic routes (addition and conde …

• Defining polymerisation only in terms of addition reactions and omitting condensation. …
