What are polymers? Through which process are they synthesized or made?

Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.

Explanation:

Polymers can be synthesized using  reactants of petrochemical or renewable origin. Polymers can be synthesized in two  methods, by step-growth and chain polymerization. Both ways of polymerization are  random processes during which chains of different lengths are formed.

The basis of step-growth polymerization is the condensation reaction.
