(a) Draw the structure of polystyrene, which is formed by polymerizing the monomer styrene, C6H5CH=CH2. (b) What monomer is used to form poly(vinyl acetate), a polymer used in paints and adhesives?
(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. Since 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.
