Polymers, composites, and methods for making polymers and composites

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.

Phenolic resin, preparation process, sizing composition for mineral fibers and resulting product

A liquid phenolic resin intended to participate in the makeup of a sizing composition for mineral fibers is essentially composed of phenol-formaldehyde and phenol-formaldehyde-glycine condensates. A process for the manufacture of the resin, the sizing composition including the resin and the insulating products based on mineral fibers sized by means of the abovementioned sizing composition are presented.
