6. In a free radical polymerization of polystyrene, GPC is used to follow conversion of styrene monomers at various reaction time. - Solvent used to dissolve reaction mixture is carbon disulfide (refractive index = 1.6) - Refractive index of styrene = 1.52 - Refractive index of polystyrene = 1.61 - Initiator is 2, 2' - Azobisisobutyronitrile (AIBN) (the amount is very small) 6.1 Explain characteristics of these two concentration detectors 6.1.1 UV-visible detector 6.1.2 Differential Refractometer detector 6.2 From 6.1 which detector you prefer to use in this experiment? Why? 6.3 Draw expected GPC chromatograms of the samples obtained from 0% conversion and 50% conversion 6.
