The polymer is then treated with concentrated sulfuric acid to sulfonate a majority of the aromatic rings in the polymer. Q.) Show the product of sulfonation of each benzene ring.Which monomer and which type of initiator can you use to synthesize each of the following polymers?

(b) Draw the structure of the cross-linked polymer B formed when A is treated with H2NCH2CH2CH2NH2 as the hardening agent.(a) Hard contact lenses, which first became popular in the 1960s, were made by polymerizing methyl methacrylate [CH2=C(CH3)CO2CH3] to form poly(methyl methacrylate) (PMMA). Draw the structure of PMMA. (b) More-comfortable softer contact lenses introduced in the 1970s were made by polymerizing hydroxyethyl methacrylate [CH2=C(CH3)CO2CH2CH2OH] to form poly(hydroxyethyl methacrylate) (poly-HEMA). Draw the structure of poly-HEMA. Because neither polymer allows oxygen from the air to pass through to the retina, newer contact lenses that are both comfortable and oxygen-permeable have now been developed.A3 Anionic polymerization of styrene is generally known to produce polymers with a narrow molecular weight distribution. Explain the reason for this.
