Abstract: Disclosed are processes for preparing sol-gel resins from phenolic compounds and aldehydes. The process includes reacting an hydroxylated benzene and a catalyst with an aldehyde to form a liquid storage stable intermediate. The storage stable intermediate may then be stored for a period of time before being utilized in a process to prepare the sol-gel resin, in either monolith or particle form, by subsequently reacting the intermediate with an hydroxylated benzene and a catalyst.

Abstract: Sol-gel resins can be prepared using one or two-step processes to produce small granules or pellets of resin that are easy to handle. The methods include agitating phenolic compounds and aldehydes in the presence of a catalyst and a solvent. The reactants are brought together over a period of time to avoid an undesirable buildup of heat within the reaction mass. Condensation of the material continues under agitation sufficient to knead the material as it gels. During this gelation, the material begins to form into smaller parts until particles, the shape of granules, are produced. The condensation continues to the degree that the material is no longer capable of sintering during packaging and storage. The material thus made can be easily discharged, packaged, portioned, and further processed.

Abstract: A formulation which contains:(1) the nucleophilic addition adduct of an imidazole and an unsaturated compound, which contains more than one imidazole moiety per molecule; and(2) an epoxy resin,is characterized in that fewer than 50 equivalent percent of the imidazole moieties in the adduct are neutralized with acid. The adduct may serve as a curing catalyst in high or low-temperature curing. The formulation is made and applied as a powder coating for coatings or as a matrix resin in laminates. It may be used in solvent-borne or liquid systems.
