    Abstract: A process is disclosed for preparing aspartic acid polycondensates. Finely dispersed aspartic acid is heated up to a temperature of at least 150 DEG C and polycondensation is carried out in the presence of a cocondensable monomer that contains at least one functional group and of acid catalysts so that the catalysts and if required the co-condensable monomers contact the aspartic acid, heated up to a temperature of at least 150 DEG C, only in the reaction zone in which polycondensation takes place.

    Abstract: The invention concerns a process for preparing fine-particle mixtures comprising between 97 and 10 wt % of at least one amphiphilic polymer whose softening temperature is above 35 DEG C, and between 3 and 90 wt % of at least one inorganic solid having a particle size of up to at most 500 mu m. According to this process the two components are heated to a temperature which is above the softening temperature of the polymer. The two components are then mixed, broken down in the molten state and rapidly cooled, to a temperature at which practically no separation occurs. The particles are optionally broken down further at temperatures of less than 50 DEG C such that the particle size is between 50 mu m and 5 mm. The invention further concerns the use of these mixtures as detergent additives.
