    摘要: Thermosetting resins are produced by blending 1 equivalent of a polyoxazolidone terminated by two vicinal epoxy groups and containing at least two oxazolidone rings with at least 1 equivalent of a polyfunctional isocyanate compound, adding 0.01 to 10% by weight of a catalyst which forms isocyanurate rings and oxazolidone rings based on the total amount of the polyoxazolidone and the isocyanate compound, and then heating the resulting composition to polymerize the composition by forming isocyanurate rings and oxazolidone rings. The resin compositions have excellent mechanical properties, and particularly excellent flexibility, and excellent thermal resistance.

    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.
