Abstract
Polymeric materials and methods for making the polymeric materials utilizing bisphenolic stillbottoms, lignosulfonates, or both are disclosed. In one embodiment, a polymer is provided that includes a condensate of bisphenolic stillbottoms, an optional phenolic compound independent of bisphenolic stillbottoms, an aldehyde, and a lignosulfonate compound. The condensate may further include an amino compound, a catalyst, or combinations thereof. Alternatively, the polymer may be free of a phenolic compound independent of bisphenolic stillbottoms. The polymers may be used in the manufacture of articles including composites, laminates and paper products.
