    摘要: A thermosettable, polymerizable resin composition comprising a polyepoxide and a polyisocyanate which is normally catalyzed by a basic curing catalyst for forming oxazolidone rings and isocyanurate rings or uredione rings is remarkably stabilized at low temperatures by incorporating a small amount of an organic electron acceptor, such as, picric acid, quinone, chloranil, or cyanoacetate ester into the composition. Since the specific electron acceptors effectively inhibit the polymerization of the reactive components in the composition at low temperatures, a shelf life of the composition is remarkably prolonged.

    摘要: A crosslinkable compound obtained by reacting an aromatic hydrocarbon-formaldehyde resin with an .alpha.,.beta.-unsaturated monocarboxylic acid or an ester thereof has no odor or very slight odor. Said crosslinkable compound can be radical polymerized at a low temperature to give a cured article having excellent electrical insulating properties. Said crosslinkable compound can also be used as one component of a resin composition containing an unsaturated polyester resin or a polybutadiene resin modified with acrylic or methacrylic acid to give an odorless or low-odor resin composition suitable for producing reinforced plastics, paints and varnishes, adhesives, electrical parts, etc.
