Abstract: The present invention relates to a solar module comprising a first layer, a solar cell arranged above the first layer and a second layer arranged above the solar cell. The first and/or the second layer comprise a fiber composite material which comprises a preferably aliphatic polyurethane polymer “dual cure” system) crosslinked thermally and by means of electromagnetic radiation. The material of the fibers of the fiber composite material is transparent at least in the region of visible light. The invention further relates to the use of this type of solar module and to a process for production thereof.

Abstract: The present invention relates to a process for producing a solids-containing PUR spray jet and also to a spray attachment, wherein a solids-containing gas stream is introduced into a liquid jet of a PUR reaction mixture.

Abstract: Polyurethane molded foams having a surface region and an interior region and comprising a flame-retardant solid, wherein the flame-retardant solid is present in the surface region in a proportion higher than a proportion of the flame-retardant solid in the interior region; processes for preparing the same; and materials comprising such foams.

Abstract: The present invention concerns a method for the treatment of polyurethane foam, wherein the polyurethane foam is obtainable from a reaction mixture comprising an ethylene oxide/propylene oxide polyol component with an OH number of ?20 mg KOH/g to ?45 mg KOH/g and an isocyanate component with an NCO content of ?20 weight-% to ?49 weight-% which is selected from the group comprising diphenylmethane diisocyanate, toluene diisocyanate, their prepolymers with an ethylene oxide/propylene oxide polyol whose OH number is from ?20 mg KOH/g to ?45 mg KOH/g and/or their allophanates, ureas, biurets, uretdiones, isocyanurates or carbodiimides. The invention further concerns a polyurethane foam which has been treated by such a method. After the foam formation has finished, the polyurethane foam is irradiated with microwave radiation and the irradiated energy, in relation to the volume accessible by the microwave radiation, is from ?1.0 kilojoules/liter to ?2.23 kilojoules/liter.

Abstract: The present invention relates to an improved process for the preparation of NCO-reactive components from fully reacted products of the isocyanate polyaddition process, in particular those based on MDI and/or TDI, using reactive solvents in a microwave field.

Abstract: The present invention relates to a process for the preparation of carbodiimide- and/or uretonimine-modified polyisocyanates by means of microwave radiation and to the use of such polyisocyanates for the synthesis of foamed and non-foamed polyurethane materials.

Abstract: The present invention relates to a process for the accelerated preparation of polyesterpolyols in equilibrium by alcoholysis using microwave radiation, and to the production foamed and non-foamed polyurethane materials from these polyesterpolyols.

Abstract: The invention relates to a method for producing chiral amino acid derivatives, characterised in that free carboxylic acid groups in an amino acid derivative are first converted into nitro ketones, and said nitro ketones are then converted into the corresponding nitro alcohols and amino alcohols by means of reduction. The invention also relates to the nitro ketones and nitro alcohols obtained as intermediate products.
