4 (Glass Transition Temperature and Polymer Repeat Unit, 10 pts) Polyvinyl chloride (PVC) and Poly(tetrafluoroethylene) (PTFE); and poly(methyl methacrylate) (PMMA) and Poly(hydroxyethyl methacrylate) (PHEMA) are common biomaterials and their monomer structures are shown below: Polytetrafluoroethylene (PTFE) a) Polyvinylchloride (PVC) H CH3 H CH3 H 0 CH3 Poly(methyl methacrylate) (PMMA) C2H4OH Poly(hydroxyethyl methacrylate) (PHEMA) b) Using your knowledge of polymer backbone flexibility, pendant group structure and polarity, main chain symmetry and polarity, determine which polymer in a) will have a higher Tg and explain why. Repeat analysis for polymers in b)
