A resist underlayer film for lithography has high solubility in a resist solvent (solvent used in lithography) for expressing good coating film forming property and a smaller selection ratio of dry etching rate as compared with a resist. A resist underlayer film-forming composition containing a novolac resin containing a structure (C) obtained by a reaction of an aromatic ring of an aromatic compound (A) with a hydroxy group-containing aromatic methylol compound (B). The aromatic compound (A) may be a component constituting the structure (C) in the novolac resin. The hydroxy group-containing aromatic methylol compound (B) may be a compound of Formula (1): ##STR00001## The hydroxy group-containing aromatic methylol compound (B) may be 2-hydroxybenzyl alcohol, 4-hydroxybenzyl alcohol, or 2,6-di-tert-butyl-4-hydroxymethyl phenol.

Examples of the present disclosure provide fluoropolymers and methods for forming and using such fluoropolymers. Fluoropolymers include polyfluorobenzoxazines and polyfluoroimides. Methods for forming polyphthalonitriles are also provided. The present disclosure is further directed to compositions containing one or more fluoropolymers and one or more metal oxides.

Disclosed are curable coating compositions, and methods of cathodic corrosion protection using the compositions. For example, a curable coating composition comprising a mixed salt of magnesium thiodialkanoate, and a method for applying the coating composition, which when applied onto a steel or other ferrous substrate provides an anticorrosive coating, effective for improving resistance to cathodic disbondment.

Ruptureable, dual reagent mono-capsules are disclosed that have a pre-formed capsule having a core composition, which includes a first reagent, encapsulated within a polymer wall, and a shell connected to an exterior surface of the polymer wall by a surfactant. The shell is made from a second reagent that is chemically bonded to the surfactant by a chemical electrostatic interaction. Upon rupture of the polymer wall of the mono-capsule, the first reagent and the second reagent chemically react with one another to form a reaction product.

A method for the manufacture of mineral wool products is disclosed. In one example, the method comprises reacting an aqueous phenol-formaldehyde resole with free formaldehyde with a first amount of urea, thereby preparing a prereact. The prereact is contacted with a second amount of urea. The resulting mixture of prereact and second amount of urea, as part of a binder, optionally with additives is applied to the surface of mineral fibers. The binder is cured on the surface of the mineral fibers. A mineral wool product with reduced emissions of formaldehyde is also disclosed.
