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.

Polymers, composites, and methods for making polymers and composites

Amino-formaldehyde resins may be prepared using formulations including formaldehyde, glycerin and at least one amino compound selected from the group consisting of urea, melamine, and mixtures thereof; under reaction conditions sufficient to prepare a resin, wherein; the amino-formaldehyde resin is prepared in a substantial absence of a sulfonating agent, ethylene glycol, and polyalkylene glycols. If the amino compound is urea, then the urea is present in a molar ratio of formaldehyde to urea ranging from 0.70 to 1.30; if the amino compound is melamine, then the melamine is present in a molar ratio of formaldehyde to melamine ranging from 1.3 to 2.2; and if the amino compound is a mixture of urea and melamine, then the mixture of urea and melamine is present in a molar ratio of formaldehyde to urea and melamine ranging from 0.35 to 1.3.

Storage stable amino-formaldehyde resins and applications thereof

An adhesive binder comprising a phenol-formaldehyde resin, polyvinyl ester resin, and a protein is disclosed. The adhesive binder is useful for preparing wood composites.

Wood composites, methods of production, and methods of manufacture thereof

Hybrid resins formed of an acylated phenol-formaldehyde (PF) resin and a polymeric phenyl isocyanate (pMDI) resin have extended shelf stability, yet cure at a rate faster than any of its components when used in conventional flakeboard, strandboard or other board making processes.

Hybrid phenol-formaldehyde and polymeric isocyanate based adhesive and methods of synthesis and use

The present invention relates to a process for the production of wood composite products consisting of combining wood particles with a binder composition, and molding or compressing the combination of wood particles and binder composition. Suitable binder compositions comprise (1) an aqueous dispersion of a blocked polyisocyanate component and (2) an aqueous solution of a phenolic resin.

Aqueous mixed pMDI/phenolic resin binders for the production of wood composite products

The present invention relates to novel blocked polyisocyanates that are soluble or dispersible in water and which contain phenolate anions in a chemically bound form as groups which provide their solubility or dispersibility. It also relates to a process for the preparation of these blocked polyisocyanates in the form of a solution or dispersion in water, optionally in the presence of coreactants, and to their use as hardeners in two-component lacquers, binders and/or adhesive formulations.
