Abstract: A textile semifinished product with at least one surface provided with an adhesive, wherein the adhesive is immobilized on the surface of the semifinished product in order to maintain the tack in a lasting manner. To this end, at least one constituent of the adhesive is partly crosslinked and the partly crosslinked constituent is the product of partial crosslinking of at least one monomer containing double bonds, the monomer containing double bonds being a partial ester prepared by the reaction of an epoxy resin with an unsaturated carboxylic acid.

Abstract: The object is to improve the prior-art production method for semi-finished textile products with enhanced toughness. The object is achieved by a method for producing a semi-finished textile product, including a toughness-enhancing material, for the production of a composite fiber component, and including the step of: applying the toughness-enhancing material to the exterior surface of individual layers forming a multi-ply fabric, multi-ply fabrics, woven textiles, knitted fabrics, matted fabrics or braided fabrics, or any combination thereof, wherein the toughness-enhancing material includes particles having a particle size in the range of 0.5 ?m to 500 ?m.

Abstract: Metal compounds of pseudohalogenides and their use as curing agents for epoxy compounds which curing agents can be produced by mixing the reactants in aqueous solution and are distinguished by a long processibility time at temperatures up to 100° C. as well as by very short curing times at temperatures in the range of 120 to 160° C.

Abstract: New initiators which are suitable for cationic polymerization have the following structure: ##STR1## such that following apply: R.sup.1 and R.sup.2 are alkyl or cycloalkyl or they, together with the S atom, form a heterocyclic ring,R.sup.3 is H or alkyl,R.sup.4, R.sup.5, R.sup.6, and R.sup.7 are H, alkyl, or alkoxy,X.sup.-- is a non-nucleophilic anion.Reaction resin mixtures with initiators of this type contain, in addition to a cationically polymerizable monomer and/or oligomer, 0.01 to 10% by mass of the initiator.

Abstract: Curable reaction resin mixtures which are suitable for stereolithography have the following composition:a cationically curable monomer and/or oligomer,an initiator with the following structure: ##STR1## where the following applies: R.sup.1 and R.sup.2 are alkyl or cycloalkyl, or together with the S atom they form a heterocyclic ring,R.sup.3 is H or alkyl,R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are H, alkyl or alkoxy,X.sup.- is a non-nucleophilic anion,and optionally a filler, pigment and/or additive.
