Abstract: A safety braking device for a sliding roof cover that is moved in translation along vehicle-fixed guides includes at least one braking element that is coupled with the sliding roof cover, and which in normal operation moves together with the sliding roof cover in translation along an associated guide. A coupling piece is movable with the sliding roof cover and makes a connection between the sliding roof cover and the braking element. The coupling piece extends into the braking element. The coupling piece displaces in the braking element upon an abrupt acceleration of the sliding roof cover relative to the guide, and deforms the braking element such that the braking element and the associated guide are jammed to prohibit further movement of the sliding roof cover along the associated guide.

Abstract: The present invention relates to wire coatings which containa) 20 to 50% by weight of a tris-2-hydroxyethyl isocyanurate-modified polyester,b) 2 to 35% by weight of a bismaleimide resin,c) 0.1 to 3% by weight of a catalyst, preferably a titanate catalyst, andd) 35 to 77% by weight of organic solvents, with respect to the total weight of the wire coating, which is 100% by weight. The invention also relates to processes for the preparation of the wire coatings according to the invention.

Abstract: Solid, fusible bismaleimide resins formed from a mixture of a bismaleimide and an aminophenol still contain from 70 to 90 mol % of unconverted bismaleimide and from 30 to 60 mol % of unconverted aminophenol.

Abstract: Heat-curable resins which are suitable for fabricating carbon fiber prepregs and fiber composites by winding and resin transfer molding contain a bismaleimide, an alkenylphenol and N-vinylpyrrolidone.

Abstract: Heat-curable bismaleimide resins containing an aromatic alkenyl compound, preferably o,o'-diallylbisphenol A, and a Lewis acid as an additive for prolonging the pot life at elevated temperatures are suitable for impregnating reinforcing fibers, rovings so impregnated having a prolonged gel time and being usable for fabrication of wound structures.

Abstract: A thickened, uncrosslinked molding composition which has a long shelf life and can be cured above 50.degree. C. comprises a liquid reactive system, a thickener, a polymerization initiator and conventional additives. The thickener is a combination of a primary aromatic amine and an isocyanate. The molding compositions, which are, in particular, SMCs or BMCs, can be processed into moldings by compression molding, injection molding or transfer molding and subsequent curing.

Abstract: Heat-curable bismaleimide resins contain a bismaleimide and a heterocyclic comonomer having terminal alkenyl or alkenyloxy groups. A preferred comonomer is 2,6-bis-(2-propenylphenoxy)-pyridine. The bismaleimide resins are suitable for the production of high performance composites.

Abstract: Novel phenol compounds of the general formula ##STR1## where X is a sulfone group or contains a sulfone group, are suitable for the preparation of epoxy resins, vinyl ester resins, bismaleimide resins and cyanate resins.

Abstract: Epoxy resins obtained from an epoxyalkyl halide and an aromatic hydroxyl-containing melamine derivative, and vinyl ester resins based on a reaction product of the epoxy resin with an unsaturated monocarboxylic acid can be cured to give molded materials having high heat distortion resistance.

Abstract: Bismaleimides having the general formula ##STR1## in which n is a whole number between 5 and 70 and --X-- is --O-- or --NH-- are prepared through the reaction of the corresponding amino-terminated polyoxybutylenes with 2 moles of maleic anhydride. They are suited as toughening agents in high grade reactive resins.
