A monoallophanate can be used in paint or adhesive compositions. The monoallophanate has the formula 1: where R, R-Rare each independently identical or different hydrocarbyl radicals having 1-8 carbon atoms, which may be branched or cyclic, or else may be integrated together to form a cyclic system, and m and n are each independently 0-2.

Monoallophanates based on alkoxysilane alkyl isocyanates

The invention relates to heat-curing powder-lacquer compositions exhibiting a matte surface after curing of the coating, as well as to a simple method for production of the same.

The invention relates to novel &#x3b2;-hydroxyalkylamides, to a method for their production and to the use thereof.

Beta-hydroxyalkylamides, method for their production and use thereof

Process for the continuous preparation of prepolymers based on phenolic resin, an oxazoline component and an epoxide in the presence of a catalyst, including supplying the phenolic resin and the oxazoline component to an extruder in a stream A; a Lewis adduct of boron trifluoride or of aluminum trichloride, or arylsulphonic acids or alkylsulphonic acids, or latent arylsulphonic acids or latent alkylsulphonic acids, in a stream B, and the epoxide in a stream C, the infeed of stream A being situated, as seen in extrusion direction, before the infeed of stream C, these reactants are mixed at a reaction temperature of 120 to 200&#xb0; C. with a residence time in the extruder of 3 seconds to 15 minutes, and then the product discharge of the extruder is cooled to a temperature of less than 45&#xb0; C. within from 30 to 60 seconds.

Process for continuous preparation of a prepolymer based on phenolic resins, oxazolines and epoxides

The invention relates to a continuous process for producing a reactive polymer based on compounds according to the structures (A1) and/or (A2) and phenolic resin in an extruder and to the reactive polymer produced according to said process and the use thereof for producing composite materials.

Continuous process for producing a reactive polymer

The invention relates to a process for the solvent-free, continuous preparation of polyureas by reacting at least one isocyanate and/or isocyanurate having at least two NCO groups with at least one diamine and/or polyamine in an extruder, intensive kneader, intensive mixer or static mixer by thorough mixing and rapid reaction by briefly heating and subsequent cooling to isolate the end product.

Process for the solvent-free, continuous preparation of polyureas

Process for preparing highly reactive (semi)crystalline and amorphous blocked polyisocyanates

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.
