The invention relates to amorphous poly-alpha-olefins, which are characterized in that said amorphous poly-alpha-olefins have a viscosity at 190° C. of less than 5000 mPas, a molar mass distribution (Mw/Mn) of 3 to 8, a quotient Mz/Mw of less than or equal to 3.0 and a quotient Mz/Mn of less than 21.0. The invention further relates to a method for producing degraded amorphous poly-alpha-olefins, in particular the amorphous poly-alpha-olefins according to the invention, and to the use of the amorphous polyalpha-olefins according to the invention or produced according to the invention in hot-melt adhesive compositions.

The invention relates to a process for the preparation of polyaddition products containing uretdione groups, prepared from a polyisocyanate-uretdione having at least two free isocyanate groups, diols and, if desired, monoalcohols or monoamines, in which the polyaddition products containing uretdione groups are prepared by a solvent-free and continuous procedure which is carried out in an intensive kneading apparatus/extruder. The invention also relates to the use of polyaddition products containing uretdione groups for PUR powder coatings and for solvent-containing, one-component stoving enamels.

Process for the preparation of polyaddition products containing uretdione groups, and their use in polyurethane coating systems

Process for the continuous preparation of hydroxyalkylamides Process for the continuous preparation of hydroxyalkylamides from carboxylic esters and alkanolamines, wherein the reaction of the starting materials is carried out in an extruder or intensive mixer by intensive mixing and brief reaction with supply of heat and simultaneous removal of the alcohol formed and the final product is then isolated.
