Most of carboxyl groups of PAA do not dissociate to –COO − + H + in water at neutral pH and in 1,4-dioxane because it is a typical weak acid as is the case with acetic acid (CH 3 COOH). Since C–C bonds on the main chain are quite rotatable at room temperature, the chain structure in 1,4-dioxane is rather close to the random coil.
