抄録
Extensional viscosities ηe(ε) of polystyrenes (PS) with high molecular weights in benzyl butyl phthalate (BBP; a good solvent for PS) and dioctyl phthalate (DOP; a θ solvent for PS) were studied in the dilute region for viscosity as a function of the extensional rate with an opposing jets extensional rheometer.<BR>The ηe(ε) data obtained with use of different orifice geometries agree with each other within experimental errors. The extensional viscosity at low ε limit, ηe0 is about three times larger than the corresponding zero-shear viscosity in accordance with Trouton's rule.<BR>In high ε region, the extensional-thickening was observed for all the solutions. The critical extensional rate ε* at which the ηe(ε) deviates from ηe0 is confirmed to be related to the longest relaxation time of the solutions.
