  • Patent number: 10184022
    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.

  • Patent number: 8343634
    Abstract: Composite panels may be prepared using a moisture resistance additive having a formulation that includes a triglyceride having a saponification value of at least 150 and an iodine value of at least 35. The additive may be used in the form of a water emulsion. The water emulsion may be prepared by dispersing the components of the additive formulation under conditions sufficient to at least partially saponify the triglyceride. The moisture resistance additive can impart resistance to moisture absorption and thickness swelling to composite panels prepared therewith.
