Hydrocarbon-aromatic hydroxyl-containing resins are prepared by (1) reacting an unsaturated hydrocarbon with an aromatic hydroxyl-containing compound in the presence of a Lewis acid, (2) neutralizing said Lewis acid with an inorganic base and (3) removing the unreacted aromatic hydroxyl-containing compound therefrom.

Halogen-containing hydrocarbon phenol cyanate resins are prepared by reacting the product resulting from reacting a hydrocarbon phenol resin with a metahalogenated hydroxymethyl phenol with a cyanogen halide.

Flame resistant polyaromatic cyanate resins with improved thermal

Polymeric compositions are prepared from ethylenically unsaturated monomeric compositions and polyarylcyanate ester compositions which have at least two arylcyanate ester moieties bridged by a polycyclic aliphatic moiety; and wherein the polyarylcyanate ester composition is substantially soluble in the ethylenically unsaturated monomeric composition.

Curable composition from ethylenically unsaturated monomers and

Laminates are prepared for reinforced expoxy resin compositions comprising (A) a reinforcing material such as fiberglass, (B) one or more epoxy resins such as a hydrocarbon-phenol eposy resin and (C) one or more epoxy resin curing agents such as a hydrocarbon-phenol resin or phenol-formaldehyde novolac resin. These laminates are particularly suitable for use in electrical applications such as the manufacture of printed circuit boards.

Laminates from epoxidized phenol-hydrocarbon adducts

Curable compositions are prepared from reinforced epoxy resin compositions comprising (A) a filler material such as silica flour, (B) one or more epoxy resins at least one of which is a hydrocarbon novolac epoxy resin such as a phenol-dicyclopentadiene epoxy novolac resin and (C) one or more epoxy resin curing agents such as phenol-formaldehyde novolac resin. These compositions are particularly suitable for use in electrical applications such as the encapsulation and subsequent protection of electrical and micro-electronic devices and circuitry and in adhesive formulations.

Durable epoxy resin

New epoxy resins result from dehydrohalogenation of the reaction product of an epihalohydrin such as epichlorohydrin with the reaction product of a trisphenol such as 1,1,1-tris(hydroxyphenyl)methane with dicyclopentadiene or an oligomer thereof. These new epoxy resins are useful in the electronics industry as encapsulants, potting compounds, laminates and the like.

Epoxy resins prepared from trisphenols and dicyclopentadiene

Improved products and reaction conditions for preparing the same result from the reaction at elevated temperatures using a combination of a trisubstituted phosphine and a soluble chromium compound as catalyst for reacting a polyepoxide with carboxylic acids composed essentially of a dicarboxylic acid, an ethylenically unsaturated monocarboxylic acid and, optionally, a saturated monocarboxylic acid.

Catalysts for reaction of carboxylic acids with polyepoxides

A radiation curable vehicle for coating and printing ink compositions consist essentially of the reaction product of a polyepoxide, a saturated dicarboxylic acid, an ethylenically unsaturated monocarboxylic acid and optionally a saturated monocarboxylic acid.
