Abstract: A metal to rubber adhesion promoter comprising the reaction product of a phenol and a substituted melamine, said phenol being ##STR1## wherein R.sub.1 through R.sub.4 are selected from the group consisting of hydrogen, cyclic and acyclic alkyl groups having from 1 to 10 carbon atoms, and a substituted melamine having the formula ##STR2## where R.sub.5 through R.sub.10 may be the same or different and are selected from the group consisting of alkyl groups having from 1 to 5 carbon atoms. The reaction product is a resin and is added to the rubber compound prior to cure. The adhesion promoter is useful in the making of tires having steel belts and in other reinforced rubber articles.

Abstract: A solid pigment composition comprises an intimate mixture of a pigment and a copolymer of an alkyl or cycloalkyl methacrylate ester and a lesser amount of an aminoalkyl methacrylate ester. The compositions are compatible with a wide range of substrates such as paints, printing inks and bulk polymers.

Abstract: A composite quasi-crystalline material made of a polymeric support matrix having disposed therein polar quasi-crystals of photochromic spiropyran complexes, believed to be of the formula A.sub.n B, in which A represents the "colorless" photochromic spiropyran molecule and B represents the colored merocyanine form which is the photolysis product of A, and n is 2 or 3. The polar quasi-crystals are present in the composite material in a substantially polar aligned form. Methods for making the composite material are also disclosed.

Abstract: Dispersions of hydrophobic substances in water are prepared by dissolving the hydrophobic substance together with an ionomeric polyaddition or condensation product in an organic, water-miscible solvent or a mixture of such a solvent with water, diluting the solution with water and removing the organic solvent. The dispersions are excellently suitable for the preparation of photographic recording materials.

Abstract: A process for pigmenting organic material of high molecular weight, which comprises the use of a compound of the formula ##STR1## in which X is a meta- or para-positioned fluorine, chlorine or bromine atom. The yellow to scarlet colorations obtained are distinguished by excellent fastness to light and atmospheric influences.

Abstract: The disclosure of this application is directed to a water-curable composition comprising a water-curable, silane modified alkylene-alkyl acrylate copolymer, a mineral filler and a halogenated flame retardant additive. These compositions are useful as extrudates about wires and cables providing insulation or jacketing thereon characterized by resistance to deformation and by flame retardancy.

Abstract: Radiation crosslinked compositions containing copolymers of ethylene and a vinyl ester or an acrylate, a hydrated inorganic filler, a higher concentration of silane than employed heretofore and a lubricant of lauric acid and ethylene-bis-stearamide exhibit physical strength properties substantially similar to a chemically crosslinked counterpart.

Abstract: Thermoplastic compositions are described comprising blends of nylon and cured ethylene-vinyl acetate (EVA) rubber.

Abstract: A synergistic stabilizer combination is provided for use in improving the resistance of polymers, such as olefin polymers and copolymers, to deterioration in physical properties upon exposure to heat. The stabilizer combination contains a quinoline compound, a diamine compound and a magnesium compound in correlated amounts. In addition, olefin polymer compositions such as an ethylene-vinyl acetate copolymer composition containing the synergistic stabilizer combination and a method for preparing the compositions are provided.
