$\sf\star\bold\purple{{ANSWER:-}}$

$\sf\implies$A process of making the monomer molecules react together in a chemical reaction and produce three dimensional networks or polymer chains is called polymerisation.

$\sf\boxed{\boxed{Degree\:of\:polymerisation}}$

• The main characteristic of polymer which determines the physical properties of polymer materials is defined as the degree of polymerisation.

• A large molecule made up of rings or chains of linked repeating subunits referred to as monomers is called polymer.

• They generally have high boiling and melting points.

$\sf\boxed{\boxed{Polymerisation\:techniques}}$

Addition polymerisation:

• Bulk polymerisation.

• Solution polymerisation.

• Suspension polymerisation.

• Emulsion polymerisation.

Condensation polymerisation:

• Melt polycondensation.

• Solution polycondensation.
