Write the monomer of the following polymer `:`
`a.` `P.M.M.A.` ,`b.` `H.D.P.E `
`c. P.A.N` , `d.` Styron
`e.` Teflon , `f.` Dieprene
`g.` Natural rubber `h`. Gutta `-` Percha
`i.` `P.P.`

Explanation

a. `P.M.M.A.implies `Polymethyl methacrylate

Monomer is methyl methacrylate
`b. H.D.P.E.implies` High `-` density polyethene
Monomer is ethene `(CH_(2)=CH_(2))`
`c. P.A.N. implies` Polyacrylonitrile
Monomer is acrlynitirle
`d.` Styron `implies` Polystyrene
Monomer is styrene `(CH_(2)=CH-Ph)`
`e.` Teflon `implies` Polytetrafluroethene
Monomer is tetrafluoroethene `(F_(2)C=CF_(2))`
`f.` Dieprene `implies` Polychloroprene

Monomer is chloroprene
`g.` Natural rubber `implies` Polyisoprene `9` all cis `-` rubber `)`
Monomer is isoprene or `2-` methyl buta `-1,3-` diene

`h.` Gutta`-` Percha `implies` Polyisoprene `(` all trans `-` rubber `)`
Monomer is isoprene as in `(g)`
`i.` `P.P.implies` Polypropene
Monomer is propene `(CH_(2)=CH-CH_(3))`
