Abstract: A curable composition consisting of A. 100 parts by weight of an epoxy resin, B. from 4 to 100 parts by weight of a conventional curing agent for epoxy resins, and C. from 0.1 to 5 parts by weight of an N-acylimidazole which possesses an aromatic acyl component which is substituted at the two positions ortho to the carbonyl group can be used to produce moldings, coatings, finishes, adhesives and composite fiber materials.

Abstract: The subjects of the invention are novel carbodiimides and/or oligomeric polycarbodiimides having terminal isocyanate, urethane and/or urea groups, obtainable e.g. by condensation with elimination of carbon dioxide of 1,3-bis(1-methyl-1-isocyanatoethyl)benzene and thereafter optionally partial or complete reaction of the free isocyanate groups of the resulting (poly)carbodiimides with aliphatic, cycloaliphatic or araliphatic amines, alcohols and/or alkoxypolyoxyalkylene alcohols, a process for their preparation and their use as a stabiliser against the hydrolytic degradation of polyaddition and polycondensation products containing ester groups.

Abstract: The invention relates to novel 4,4'-disubstituted bis(2,6-diisopropylphenyl)carbodiimides of the formula (I) in which R is a 1-methyl-1-phenylethyl, phenoxy or tert-butyl radical, to a process for their preparation and to their use as stabilisers with respect to the hydrolytic degradation of ester group-containing products of addition and condensation polymerisation, and to the novel compounds which can be used to prepare them, namely 4-(1-methyl-1-phenylethyl)-2,6-diisopropylphenyl, 4-phenoxy-2,6-diisopropylphenyl and 4-tert-butyl-2,6-diisopropylphenyl isocyanates.

Abstract: The invention relates to fibre composites consisting of prepreg layers which are bonded to one another by intermediate layers. The prepreg layers consist of laid webs impregnated with curable resins. The intermediate layers contain regions of flexible polymer films which cover 10 to 90% of the surface of the prepreg layers. The polymer films are applied as an aqueous dispersion to the prepreg layers, and the layers are pressed after removal of the water. The composites are suitable as structural components for the aerospace industry and in the automotive industry.

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.
