    Abstract: The invention concerns polyacetal-block-containing polymers obtained by polymerizing, in the presence of initiators, carboxylic acid esters containing aldehyde groups and by reacting the polymers with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids and optionally hydrolysing the ester groups thus incorporated in the polymer. The invention also concerns a method of producing polymers containing polyacetal blocks by polymerizing carboxylic acid esters containing aldehyde groups in the presence of initiators and reacting the polyacetals containing terminal hydroxy groups thus obtained with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids, plus the use of the polymers thus obtained as additives in phosphate-free and phosphate-reduced washing and cleaning agents, as scale inhibitors and as dispersants for pigments.

    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 ~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 ~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.
