Abstract
An absorbent article is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a synthetic superabsorbent polymer derived from a first renewable resource via at least one intermediate compound, wherein said superabsorbent polymer exhibits a defined Saline Flow Conductivity value and Absorption Against Pressure value. Alternately, an absorbent article is disclosed having a synthetic polyolefin derived from a first renewable resource via at least one intermediate compound. The synthetic polyolefin exhibits defined performance characteristics making the polyolefin particularly useful in certain components of the absorbent article. Methods for making the aforementioned absorbent articles are also disclosed.
