Answer : A Polymer refers to a molecule prepared through the inter-molecular linkage among the similar or non-identical kinds of smaller molecules (known as monomers).
Orlon is also called polyacrylonitrile. It is used in the garment industry. It is a highly resistive fibre to sunlight and greenhouse gas. It is produced as a result of the polymerization process of acrylonitrile (also known as acrolein). Thus, Orlon is a polymer of acrylonitrile.
