Polymers, composites, and methods for making polymers and composites
View Patent ↗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.
