Question

Which of the following polymers can be made by anionic addition polymerization mechanism?
This question has multiple correct options
$A.$ $PVC$
$B.$ $PAN$
$C.$ Teflon
$D.$ $PP$

Answer 1

Anionic addition polymerization is a form of chain-growth polymerization that involves the polymerization of vinyl monomers with strong electronegative groups such as fluorine, chlorine etc. The anionic addition polymerization is carried out through a carbanion active species.

Complete answer:
As we know anionic addition polymerization is an ionic polymerization of vinyl monomers with strong electronegative groups such as Grignard reagent and metal alkoxide.
There are three steps in polymerization of monomers: chain initiated, chain propagation and chain terminal, In anionic addition polymerization reaction is initiated with growing chain end carrying negative charge and counter ion. Now we know enough about anionic addition polymerization. Let see which of the following polymers undergo anionic addition polymerization.
There are three polymers which undergo anionic addition polymerization namely, $PVC$ ,$PP$ and Teflon.

Hence, the correct options are $A$ , $C$ and $D$ .

Note:
$PVC$ : Polyvinyl chloride is a synthetic polymers, it is produced in an addition polymerization reaction using vinyl chloride(monomers)
$PAN$ : It is named as polyacrylonitrile, it is also known as polyvinyl cyanide. Almost all $PAN$ are copolymers made from a mixture of monomers with acrylonitrile as the main monomer.
Teflon: It’s chemical name is Polytetrafluoroethylene, it is made with four ingredients fluorspar, hydrofluoric acid, chloroform and water.
$PP$ : its name is polypropylene, it is a thermoplastic polymer used in a wide variety of applications. It is formed with addition of propylene monomers.
