Abstract: This invention is addressed to an improved size composition for use in the treatment of glass fibers in the manufacture of glass fiber textiles, glass fiber reinforced plastics, and glass fiber reinforced elastomeric products wherein the size is formulated to contain, as the essential ingredients, a polybutadiene graft copolymer and a glass fiber anchoring agent. Bundles of glass fibers sized with the composition of the invention are particularly well suited for impregnation with an elastomer compatible material containing a resorcinol-aldehyde resin component and an elastomer component for use in the manufacture of glass fiber reinforced elastomeric products.

Abstract: A hardenable binder composition is disclosed. The composition comprises a phenolic resin, hydroxyethylcellulose and a silane. The hydroxyethylcellulose being added in an amount sufficient to increase the wet tensile strength of the binder composition after cure thereof.

Abstract: We have found that if we add a polyhydric phenolic compound such as resorcinol to monohydric phenolic resin/cement systems, we can shorten the gel time sufficiently to use the systems in producing walls. The walls generally are cylindrical and serve to confine a liquid. These systems are especially good for producing large diameter, continuous pipe.

Abstract: We have developed molding compounds from cement in combination with a nylon or polyester resin. We form the resin in the presence of the cement. We can use these molding compounds to form molded articles which have good fire resistance.

Abstract: We have developed a polyvinyl chloride foam with a smooth surface and uniform cell size. The foams also are resilient and abrasion resistant, making them especially suited for use in carpeting materials. To do this, we add along chain silane or epoxide to the foam.

Abstract: We have developed new and useful epoxy resins which have excellent fire resistance. We prepare these resins by using phosphorus trihalides or phosphorus oxyhalides to cure conventional epoxy resins.

Abstract: A binder composition for use in the manufacture of wool-like and board-like masses of intermeshed, randomly oriented vitreous fibers comprising a thermo setting phenolic resin and an organo silicon component in the form of a metal salt of an organo silane.
