Question

Poly (vinyl pyrrolidone), prepared from N-vinylpyrrolidone, is used in cosmetics and as a synthetic substitute for blood. Draw a representative segment of the polymer.

Short answer

Answer

Step-by-step solution

Polymerization

Polymerization is the formation of chain-like or network molecules, called polymers, from relatively small molecules called monomers.

Representative segment of Poly (vinyl pyrrolidone):

The representative segment of a polymer means a repetitive unit from which the polymer is made. Here the alkene carbons of N-vinylpyrrolidone join with other monomer units to give Poly (vinyl pyrrolidone).
