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.
Claims16
A polymer comprising:
- a condensate comprising:
- from about 1 wt. % to about 20 wt. % of bisphenolic stillbottoms;
- an optional phenolic compound independent of bisphenolic stillbottoms;
- from about 10 wt. % to about 40 wt. % an aldehyde;
- from about 5 wt. % to about 20 wt. % of a lignosulfonate compound;
- from about 5 wt. % to about 12 wt % of catalyst;
- from about 5 wt. % to about 20 wt. % of amino compound;
- and
- from about 40 wt. % to about 60 wt. % of water, wherein the total weight percent (wt. %) is 100%.
A method of making a polymer, the method comprising:
- mixing and reacting:
- from about 10 wt. % to about 40 wt. % of an aldehyde,
- from about 5 wt. % to about 20 wt. % of a lignosulfonate compound, and
- from about 1 wt. % to about 20 wt. % of bisphenolic stillbottoms;
- from about 5 wt. % to about 12 wt. % of catalyst;
- from about 5 wt. % to about 20 wt. % of amino compound;
- and
- from about 40 wt. % to about 60 wt. % of water, wherein the total weight percent (wt. %) is 100%.
