The influence of temperature on the sorption of benzocaine by nylon 6 from aqueous cosolvents.
The influence of temperature on the sorption of benzocaine by nylon 6 powder from aqueous cosolvents has been assessed. At about 30 degrees discontinuities appear in the Van't Hoff plots for sorption from water and aqueous PEG 400, which may be attributed to transitional changes in the polymer structure. No such discontinuities are apparent for sorption from aqueous ethanol over the temperature range 15-60 degrees, which is indicative of plasticizaton by this cosolvent.
