摘要： A thermosettable resin composition is prepared by admixing a liquid mixture of thermosettable resins such as a polyepoxide and amorphous thermoplastic polymer particles such as a polyetherimide to form a homogeneous cured resin composition. The particles have an average diameter of from 0.5-50 micrometers, a surface area of at least 1.0 m.sup.2 /g, a dissolution temperature of at least 50.degree. C., and are essentially insoluble in the thermosettable resin at temperatures of up to 15.degree. C. below the dissolution temperature but are completely dissolved at a temperature of at least 20.degree. C. below the cure temperature of the resin.

摘要： A method of improving epoxy resin compositions to provide a cured resin having improved glass transition temperature and toughness characteristics is provided. The method includes providing in an epoxy resin composition an effective amount of a substituted fluorene unit in the composition. The fluorene component acts as a chain extension agent and provides for increased glass transition temperature and less cross-link density. As a result, improved toughness occurs. In preferred applications a toughening agent is provided in the resin composition, to further enhance toughness. Preferred resin compositions, cured resins and methods of providing improved cured resins are also provided.

摘要： A building panel for exterior and interior wall and roof surfaces comprises an elongated body formed of relatively thin, molded hardboard having upper and lower edges, opposite ends, an outer face adapted for exposure to the weather and a back face generally following the contour thereof. The body includes a lower edge portion extending upwardly and outwardly of the lower edge of the panel and integralling joining an intermediate fascia portion spaced outwardly of the lower edge. An upper edge portion integrally joins an upper edge of the intermediate fascia portion and includes an upwardly and outwardly extending segment adapted to underlie a lower edge portion of a panel(s) laid up in a next higher course. The upper edge portion also includes a second segment extending between the first segment and the upper edge of the panel and this second segment is generally parallel of the intermedate fascia panel portion and is adapted to underlie a portion of an intermediate fascia portion of a panel(s) laid up in a next higher course. The upper edge portion is formed with a plurality of longitudinally spaced apart, fastener receiving depressions extending inwardly of an outer face of the second segment of the upper edge portion. Longitudinally extending slot means are cut through the thin molded hardboard in the depressions between the inner and outer faces for receiving the shank of a nail or other fastener for securing the panels in place.
