✦ Synopsis

Since linear, weak-acid polyelectrolytes respond to neutral salt just like their crosslinked analogs, their equilibria have been presumed to be as amenable to analysis with the Gibbs-Donnan approach as the gels. To examine this possibility this approach has been used to estimate solvent uptake by carboxymethyldextran and poly(acrylic acid) in the course of their neutralization with standard base. These estimates have been compared with estimates obtained for the same parameter by using the ion-condensation model of Manning.

The sensitive response of weak-acid ion exchangers to counterion concentrations in the aqueous phase has been attributed to a Donnan potential term. By correcting for this term a constant pK a has, in a number of cases, been resolved for the repeating unit at each point of their titration with base.

In food packaging applications where low-density polyethylene (LDPE) ®lm containing a-tocopherol is used, the antioxidant may have a dual function, i.e. to protect the polymer from oxidative degradation during processing, and to delay the onset of oxidation of the packaged foodstuff during storage.
