Known to be poor solvent of polymer polystyrene, solvent cyclohexane is known to be most effective at 34.5oC (Ɵ temperature). We predicted that the proliferation of polymer chains would change as temperaturs moved above or below Ɵ temperature .
We used the ELSZ-2000ZS temperature gradient function to measure the dynamic light scattering of a cyclohexane solution of polystyrene (Mw = 422,000: product of Toso) as well as the effects of changing temperatures on hydrodynamic diamter (2 Rh).
