B. Natural rubber	ii. Caprolactum
C. Nylon-6	iii. Isoprene
D. PVC	iv. Acrilonitrile

1)

Explanation:- 

PAN - PAN is known as Polyacrylonitrile, Polyvinyl cyanide, Creslan 61. PAN is a copolymer made of acrylonitrile monomers. 

• Natural Rubber -  Isoprene is the monomer of natural rubber. The chemical name of isoprene is 2-methyl-1,3, butadiene

.

• Nylon-6 - Nylon-6 is made up of monomers of Caprolactam.

• PVC - The full form of PVC is Polyvinyl Chloride. It is made of the monomer units of Chloroethene or vinyl chloride.

Additional Information

•  The word ‘polymer’ is coined from two Greek words: poly means many and mer means unit or part. The process of formation of polymers from respective monomers is called polymerization. 
• The addition polymerization of acrylonitrile in presence of a peroxide catalyst leads to the formation of polyacrylonitrile.
• Polyacrylonitrile is used as a substitute for wool in making commercial fibers as orlon or Acrilan. Nylon 6 is obtained by heating caprolactam with water at a high temperature. Nylon 6 is used for the manufacture of tire cords, fabrics, and ropes.
