摘要： A thermosetting resin composition is disclosed which comprises a fusible product obtained by a method including the steps of:providing a mixture which comprises (a) a raw material containing one or more condensed polynuclear aromatic compounds having at least two condensed benzene rings, (b) a crosslinking agent containing an aromatic compound having one or more aldehyde groups directly bonded to the aromatic nuclei thereof, and (c) an acid catalyst; andreacting the mixture at a temperature sufficient to effect the crosslinking of the one or more condensed polynuclear aromatic compounds, thereby to obtain the fusible product. A further heat treatment of the thermosetting resin composition gives a COPNA resin which is an infusible, insoluble, condensed, polynuclear aromatic hydrocarbon resin.

摘要： A novel reformed mesophase pitch having a mesophase content MC of between 40 and 100%, a quinoline-insoluble content QI of between 5 and 70 weight % and anisotropic domains forming a continuous phase. The reformed mesophase pitch is obtained by heat-treating a dormant mesophase pitch which comprises dormant anisotropic components which are partially hydrogenated, polycyclic polycondensed ring aromatic hydrocarbons derived from the mesophase of a mesophase pitch by hydrogenation of the mesophase and which are soluble in quinoline. The dormant mesophase pitch is optically isotropic in nature but, upon being subjected to shear forces in one direction, capable of being oriented in said direction. Preferably, the reformed mesophase pitch has a softening point SP in .degree.C. satisfying the following conditions:when 40 .ltoreq.MC

摘要： A condensed polycyclic, polynuclear aromatic thermosetting resin with improved moldability which is prevented from forming a cloud on a mold during molding is disclosed. The resin is a prepolymer derived by condensation polymerization of a condensed polycyclic aromatic compound or a mixture thereof with a monocyclic aromatic compounds and an aromatic compound having at least two hydroxymethyl groups as a crosslinking agent in the presence of an acid catalyst. The resin has a flow temperature of not higher than 150.degree. C. The acid catalyst is water-insoluble or when it is water-soluble the resin has an insolubilized acid ratio of at least 50%. The resin is useful in the manufacture of thermoset molded articles having good heat resistance and good mechanical and electrical properties. It can be blended with a filler and/or reinforcing agent to form a molding compound.

摘要： A ferromagnetic organic substance having a triaryl methane structure and a free radical concentration of methine carbon positions of at least 10.sup.17 radicals/g, preferably at least 10.sup.18 radials/g, is provided by polycondensing a condensed polynuclear aromatic compound or an electron donating group substituted monocyclic aromatic compound with an aromatic aldehyde in the presence of an acid catalyst, to produce a precondensate having a softening point between 30.degree. C. and 120.degree. C. and being soluble in various organic solvents, and subjecting the resulting precondensate to a dehydrogenation treatment and a purification treatment, followed by molding. Alternatively, a preferable ferromagnetic organic substance having a triaryl methane structure is also manufactured by self-polycondensing an aromatic derivative having at least one electron donating group and at least one aldehyde group in the presence of an acid catalyst and then dehydrogenating the resulting polymer by light-irradiation and/or treatment with an oxidizing agent.
