Abstract: The invention relates to a process for the production of stress-cracking-resistant mouldings from heat-resistant aromatic polythioetherimides by thermoforming and subsequent crosslinking of the polymer. This crosslinking is carried out until the soluble contents of the polymer have been reduced to a value below 60% without any significant increase in the glass transition temperature. It can also be carried out until the soluble contents have been reduced to a value below 5%, in which case the glass transition temperature of the moulding increases by at least 20 DEG C.

Abstract: A solvent-free curable composition has a long shelf life and consists of A 100 parts by weight of an epoxy resin and B from 10 to 100 parts by weight of, as a curing agent for the epoxy resin, an aromatic diamine containing groups, with or without C from 0.01 to 5 parts by weight of an accelerator, the curing agent for the epoxy resin being finely dispersed in the latter and preferably having a particle size of less than 10 mu m. The preferred epoxy resin curing agent is 4,4'-diaminodiphenyl ketone. The curable composition is used in particular for the preparation of fiber-reinforced materials.

Abstract: In the process, a mixture of bismaleimide and aminophenol is heated in the presence of an amine as addition catalyst and in the presence of an inhibitor, vinyl or allyl monomers and, if desired, epoxy resins and peroxide initiators are added, and the mixture, as a melt, is applied to reinforcing fibres. The prepregs and semifinished products can be cured to form composite materials for the automotive and aerospace industries.

Abstract: A resin mixture for the production of high-temperature-resistant moulded materials, comprising A. 100 parts by weight of an epoxy resin B. From 10 to 150 parts by weight of a curing agent, preferably diaminodiphenyl sulphone. The epoxy resin is a product of the reaction of epichlorohydrin with a polyamine of the formula where the mean degree of polymerisation n is between 0.2 and 2.0.
